Used Fuel Tanks as Holding and Water Tanks

[HB of CJ]

Yeah...I'm still eyeballing the used tanks as gas (diesel fuel) tanks.  The kinda square ones will fit in various places/spaces including a fifty in space #1...just in front of the driver's side rear driver, (where the batteries are right now) #2...(a 100) just behind the right front wheel where the trunk is right now and #3 and #4 (both 75's) just behind the rear drivers on each side.  Diesel electric Crown 10 wheeler. 

Space #1 will dicate deleting the planned sunken tub/shower pan.  Oh well.  I am finding out that the design stage/phase is a lot of fun, but involves gives and takes, plus the little fact that the weights and balances have to end up fairly close when done.  Also...where in heck are the water, holding, batteries and APU going to go?  The world wonders plus me. CROWNS FOREVER!!

CJ- I had many of the challenges you do since I used a transit bus.  I does have 22" space between the bottom of the floor and the body skirt.  If you're putting the bathroom in the rear (a common design on Crowns) then the tanks should be there also.  I have a rear queen bed that has the 130 gal water tank, two water pumps, hot and cold manifold system, and two 10gal elec water heaters under.  This worked out well since my wheel wells dictated the bed to be raised to have the proper sitting height when over the wheel wells (with 5'5" of head room).  I removed the original A/C & heating system just in front of the rear axle where I installed the 45 gal black tank, 85 gal gray tank and two additional 8D house batteries.  On yours, you could put the tanks to either side of the transmission-just make sure you also install a heat shield between the tank and the transmission to keep the tanks from melting.  My 10kw Powertech generator (I have 3 roof airs) is next to the drivers seat like a front engine with the radiator remote mounted under the drivers seat with a squirrel cage blower.  It is possible to install all your goodies under a Crown-just have to be creative.  Good Luck, TomC
