Any direction as to the best way to travel and preserve the function would be greatly appreciated. One big time problem is also keeping the back of our coach cool, was 110 in Vegas the whole weekend we were there.
House batteries should charge from the engine alternator while you're driving, and from rooftop solar as long as you're in the sun, including
when you're driving.
If the house batteries are dying on the road, you may be running too much at one time, especially if some of it is 120vAC through the inverter. The alternator may be charging the batteries but not fast enough to keep up with the drain from the appliances in use.
It may also/instead be that the relay known as the BIM (Battery Isolation Manager) is not allowing the house batteries to connect to the chassis electrical system to charge from the alternator.
Your dealer is wrong about one thing: you can
run the generator on the road, as long as you have enough propane on board and it has the proper amount of oil. The generator has a low-oil shutoff that can be fooled into thinking the oil is too low if you're driving a lot of steep grades, if the generator crankcase is even slightly low to begin with.
But if you run the generator on the road, the rear-seat passengers will need to use headphones to watch television or play videogames, because they'll be sitting right on top of the generator and it's LOUD when you're sitting on top of it.
Each new Interstate model has more electrical gizmos installed than the previous model, but house battery capacity never increases from one model year to the next. So the newer the van, the less time you have between battery recharges, all other things being equal.
