Just because it is done by a paid professional doesn’t mean it is done right.

Since I do almost all my own work with the exception of the highly technical that deals with little electrics running up and down wires, or specialized skills using big expensive equipment I get to screw up and repair my own bus.

I am in the middle of finding and fixing air leaks. I admit is does not require a PHD to determine if bubbles in soapy water mean there is a leak, but it does require some skills to replace fittings or pneumatic components so the part is leak free. I just got done repairing my repairs on a pneumatic manifold that I thought I took great pains assembling, but it still leaked. Of course there were over 100 joints, 11 valves, and it used 11 compression fittings. Now it is leak free. Would a pipe fitter or plumber have done any better? I have no clue. Will I continue to put stuff back together and then have to repair my repair? Probably.

Just for information EVERY single pneumatic device has a standard for what defines leak free, and so far nothing I have bought defines leak free in absolute terms, even items I consider that should be leak free. They all use an allowable leak rate such as one bubble per minute or second or whatever their standard is. When I reassemble something I am trying to make my joints for fittings, and valves leak free, meaning no bubbles. I am not a professional, but I try to live up to what I think are realistic standards whether I am rewiring something, changing fittings, replacing air bags or whatever. Should not professionals meet such standards? When I am done I don't want leaky joints, scratched wheels, greasy hand prints, loose electrical connections, or misaligned parts. Why shouldn't people we pay have the same standards?

because people who pay by the hour thinks every job should only take a half hour...
and people who pay flat rate think that every shop is set-up like an SAE time lab....with never seen dirt or grease and grime...

LOL I wanted to add a TV to the Crestron System they said $150.00 I said no way I'll do it myself that little deal only cost me $700.00 to have the system up and running again I had everything screwed up including the POS (point of sale)

Clifford, you just identified the problem in current coaches and those issues are going to trickle down to homebuilders of the future.

Our coaches today use remotes, such as Crestron systems to operate everything. So when you want to change TVs you have to reprogram the system to reflect the change of devices.

But the house is not the only thing affected. Current models of cars, coaches and other vehicles are loaded with ECMs and all the electrical systems are multiplexed. The good news is the new electrical systems have far less wiring, fewer relays, switches and circuit breakers. But the bad news is the systems have internal diagnostics that shut down systems when something is out of range. What that means is the multiplex system modules are looking at current draw and if there is a deviation the system opens the circuit because it sees the variation as a defect or a problem. That means if in 2050 someone buys a seated Prevost to convert to a motorhome he cannot even change the type of headlights without reprogramming the multiplex system.
