New to camper vans
So I bought a 2000 Coach House 190rs a few months ago. I'm still in the process of getting ready to hit the road, and I'm gradually discovering the problems the seller did not disclose. I have a binder full of materials, mostly consisting of manuals for the various options, but I need some help sorting out how the systems work together and how to bring things up to snuff. So I have some simple (I like "simple" better than "dumb") questions.
This wide body coach is built on a Dodge RAM 3500. I've heard that these have some handling problems. I've looked into wheel extenders and will probably get those soon. What would be the best shocks?
There are two marine house batteries. These should be charged by the engine's alternator as I drive, right?
If the house batteries are charged, I should be able to use interior electrics such as the microwave, coffee maker, and house lights, right? Also, shouldn't the onboard generator be started by the house batteries?
The generator runs on gasoline. If I run the house AC and generator overnight, will it drain the fuel tank and leave me stranded?
There is a Dometic fridge/freezer, but doesn't seem to work. Are these expensive to repair? How can I troubleshoot this problem?
The van has air assist rear suspension. The seller told me I would have to inflate the air bags "by hand," which is no problem because I always carry a jump box with a built in compressor, but one of the air bags leaked down overnight. If I get that fixed, could I expect the system to hold pressure, or does the air assist require its own compressor for constant or frequent pressure adjustments?
The van AC isn't cooling. Blower motor runs, and I can see the actuator for the blend door move when I switch from AC to heat, but I get no air from the dash vents, only the windshield and floor vents, regardless of the setting. There is no cabin air filter, so that eliminates one potential cause. The dash fan works on only two of its four settings. I replaced the resistor. To replace the fan switch and connector, do I have to get the whole dash off?
I apologize for such a long post and so many questions, but if anyone has the same or similar van, I would really appreciate your input.
