Seeking your input on a new project.

Friends, Bus Nuts, Conversionmen,

We've just posted our intentions on a new project (the "Silverliner") here:

http://www.busconversions.com/bbs/index.php?topic=23466.0

We're about to spend thousands of dollars acquiring the building supplies, so before we do, we'd love your critical feedback on our plans. 

THANKS!!

I'm the bottom of the bucket as far as designs go , however your window a/c won't do... And the fridge .. My wife and I fulltime and have an 18 cubic foot fridge....2 adults and the munchkins your going to be stopping every other day to resupply... Amusing at first but it'll get old mighty fast... Also whatever a/c you get I would go with something equipped with a soft start system so your little genny doesn't keel over and I also missed anything about insulation....what are your plans there?

Great looking 5C. Good find.

Good luck with your project!

Looks like a great bus, good find!  I full timed in a 35" 5c with 2 people. We had a 12 cu ft apartment size fridge and it was adequit but for 2 people! Toss in 2 kids, no way. I had experience with an RV refrigerator and knew they were too small.

Since you have a bit of time, try to experiment, partition off your fridge at home and see how much space you can live with for how many days, comfortably. You may be far more flexible and resourceful than me. You can do this for closets and pantry's and such also.

Many people have a 2 car garage full of stuff and go buy a 10X10 shed, they start moving their stuff into the shed and quickly realize they need a bigger shed or a garage sale.Try not to shoot yourself in the foot space wise.  Lay stuff out and see what you really need, wheres the toy bin and dirty cloths go? I completely over looked dirty cloths space in my planning.   

I do not like the window AC idea, but that is my opinion.  If you decide to go that route do a complete roof air pre installation. Frame them in and run wiring including thermostat wire if needed. Then you can add roof air as time and money permit. A bus will be unlivable without front air in FL. Of course someone will pipe up with I've lived in my bus in FL for 25 years with no air conditioning    So like I say just my opinion and worth what you pay for it.   Just do not cut hole in roof until needed.

The rolling office chairs for drive and passenger, no way no how!

Some time spent looking at other buses would be worth its weight in gold and a wise investment of time.

Rule of thumb,  Time to do conversion,   take what you are planning and TRIPLE it.   Money, at least DOUBLE what you are planning .

Good luck and welcome to the madness.     JIm

jjrbus, smelly clothes. good one. most people don't think about that. wife's idea was find an old haseck (sp) and cut a hole in the bottom to dump smelly socks etc into lower bay.
worked great.

Will be a difficult build as you have laid out. But that is what makes this hobby great! Go for it. Thinking outside the box is what it is all about...Do some research on your hvac. Suggest minni split  inverter technology. Probably two 9000 BTU heat and cool would serve you well from the teens to 100F.  Would only pull a max of 13 amps. where two roof tops or window ac would pull up to 40 amps on start up.  Also look into induction cook tops. Much more efficient than drop in ranges. Toaster ovens or the induction dutch ovens can supply oven needs. Saves space and dollars. Eliminate LP  from the coach. Led lighting is inexpensive also.  Good luck    Bob

Gents, thanks for the feedback!  The fridge is now being revisited.  And the feedback on my genius window AC idea has been clear and consistent, so I'm looking into mini-splits.  Many thanks!

Now that that's oh of the way your bus and your ideas are AWESOME!! Being able to full time with the kids will be an amazing experience for all of you! And the adventures to come will be equally as amusing !

Looks fantastic!  We used tape on the floor in a previous conversion to determine how much "walk around" space we had.  Your drawings are fabulous.  I'm not familliar with the MC5's but don't cover over the interior access to the engine.  In some coaches it's on the riser for the back seat and in some it's on the floor at the rear.  We had to tear apart our entire bedroom in our coach to change the starter.  We now have a removable hatch to access the engine compartment.

Good point qayqayt,

there are two engine access hatches on a 5C. Don't cover them up. Make sure you can lift the bed to get to them.

Mike and Gigi:

Check out used generators on Craigs list or even in local large wrecking yards. Yours is way too small! And the idea of "electric start" means you don't have to go outside in the middle of a rain or snow storm to pull its rope and get it started. The second thing is your presently-selected genny will probably run 5 or six hours until it runs out of fuel. Then you will be going outside again under hurricane conditions to refill it.

$1,000 for a good used electric-start genny (a Kohler or an Onan for example) is doable: You just have to hunt around.

Have you considered all the implications of running a 12v house system on a 24v bus?  You might want to rethink that.  Remember that your engine alternator is an enormous source of power to charge house batteries if you design your system properly.

I would also advise you to reconsider separating the panels for the air conditioning and the rest of the coach.  At the very least, they should be co-located.  Otherwise it will be very difficult to move loads around later.  For example, you might find it useful to be able to run one of your air conditioners from the inverter while rolling (your coach alternator is more than capable of providing enough power to do this).

Moreover, your plan shows "50 amps, 115 volts" but you are required to have a 50-amp. 240/120-volt split-phase system on a coach like this.  You will need to account for how you will balance loads between the two legs of such a split system.

I am assuming that the lighting is shown in the plans as PAR-cans simply because that's a convenient built-in component in your drawing program.  (As I also assume you are not really planning to use a five-point-base office chair to drive .  I strongly recommend that you use all low-profile LED fixtures with warm white LEDs for your house lighting.

You did not include any details on plumbing, tankage, LPG (if desired) or heating.  Those are an integral part of the design and go hand-in-hand with electrical and A/C systems, so you'll want to get those integrated to the drawings before getting too far afield.

I will add my voice to the chorus about the window A/C.

I disagree with others on the size of the fridge -- we can go for 17 days of desert boondocking with our high-efficiency 7.5' under-counter model.  However, if you plan to get a 120-vac model rather than an LP or Dc model, you might find that a 2k inverter is undersized for your full complement of appliances.

Thanks for the head's-up.  Will plan accordingly.  -Mike

Sean, I found your discussions on this in the archives after Sam 4106 pointed out the same thing.  Here was my response to Sam:

This one requires more research - and I've been digging around the archived threads on this tonight.  One concern I have is whether I'll risk burning out the alternator on my 5C with the additional load?  Is there even a risk of this?  Would I be leaving much low-cost energy on the table by not tapping into this source?  I'm quite open to going this route if it makes sense and if my noggin can handle the added complexity of tying the chassis and house systems together.  Sean's Odessey website has great info, but I'm still not fully understanding it.  Thoughts anyone? 

I'm going to take a stab at revising the electrical for 24v house system.  I'll post it soon and would very much appreciate your review.

I would also advise you to reconsider separating the panels for the air conditioning and the rest of the coach.  At the very least, they should be co-located.  Otherwise it will be very difficult to move loads around later.  For example, you might find it useful to be able to run one of your air conditioners from the inverter while rolling (your coach alternator is more than capable of providing enough power to do this).

I left this as a separate system to avoid overloading the inverter and because I would not run the AC off my house batteries.  But this plan was made before I considered tying into the engine alternator.  If we tied it to the alternator, that would sway me toward removing the OTR air conditioner, which would free up valuable space in this 35-footer.  Not sure which way to go here.

Moreover, your plan shows "50 amps, 115 volts" but you are required to have a 50-amp. 240/120-volt split-phase system on a coach like this.  You will need to account for how you will balance loads between the two legs of such a split system.

Learned this from Sam last night as well; we haven't been to a campground before and ddn't realize it was 240.  At 50 amp, I probably shoulda known.  Can you describe how to "balance loads between the two legs?"  I'm okay with electrical stuff, but have zero experience/knowledge of 240 (except when I cobbled together my welder's NEMA plug).

I am assuming that the lighting is shown in the plans as PAR-cans simply because that's a convenient built-in component in your drawing program.  (As I also assume you are not really planning to use a five-point-base office chair to drive .  I strongly recommend that you use all low-profile LED fixtures with warm white LEDs for your house lighting.

Your assumptions are correct.  Gigi is using Revit to draw the plans, and it doesn't have air-ride captains chairs in the details library   Where did you purchase your LEDs? 

You did not include any details on plumbing, tankage, LPG (if desired) or heating.  Those are an integral part of the design and go hand-in-hand with electrical and A/C systems, so you'll want to get those integrated to the drawings before getting too far afield.

Those plans are all in my head -- haven't been transmitted to the project architect because she's been tied up packing for our upcoming move.  But here's the summary:

•   Tankage = [100 gal freshwater tank under bed & 100 gallon grey/black tank in rear bay. The grey/black is made out of plywood/fiberglass (what a mess and PITA that was), spans the bay and has 3" valterra valves on both sides.  The architect / video engineer is putting together our first youtube video of this project.
•   Plumbin is pretty straight forward and is basically taken out of the Bus Converter's Bible.  The only open questions I have are (1) which pump should we buy, (2) which LP tankless heater should we buy, and (3) should I include radiator misters on a stand-alone system running distilled water?
•   We will have LP for the kitchen burners, two heaters, the water heater, and a BBQ grill on home-made sliders in the bay.

I disagree with others on the size of the fridge -- we can go for 17 days of desert boondocking with our high-efficiency 7.5' under-counter model.  However, if you plan to get a 120-vac model rather than an LP or Dc model, you might find that a 2k inverter is undersized for your full complement of appliances.

I am planning on a 120 fridge due to cost.  But I found one of your posts in the archives where you mention that one may purchase a 24v fridge for about the the price as a 120vac model.  Can you recommend a supplier?  I selected the 2000 watt inverter on the presumption that the AC would never be run through it.  I'm still leaning in that direction but am open to suggestion.

Sean, thanks very much for sharing your knowledge and experience.  -Mike
