Would that be "Clark", "Coral" or "Anne of Green" then?
Diesel vs. gas - power might be an issue when towing or in hilly terrain.
My 2002 Rt is challenged on steep climbs as it only has a gas powered Chevy small block 350 V8.
It does get around 15 mpUSg, though.
I think a diesel engine could better handle this type of abuse.
Generators - gas versus LPG. Mine is an Onan Microlite, 2800 watt gas genset and I
think it's noisy. I'm currently looking into modified exhaust systems to quiet it. Many
campgrounds public and private have noise regulations requiring gens be run at specific
times.
Parking: Varies, but I think whatever fits between the lines is legal. Most Bs do, or are very close.
Financing: Get the best deal you can where ever that might be.
Test drives: Search online for Bs for sale near you, and call/email and ask if they'll take you for a spin
and let you try it. They pretty much drive like a cargo van with a weight problem. You get the hang of it
pretty quickly.
There are quite a few brands but it usually comes down to age/condition/mileage/price/options and personal preference.
When you actually start searching in earnest, and seeing them in person, you'll just know when you've found the right van.
Pros/cons - My main issue with our 2002 Roadtrek is the aisle shower or lack of a separate shower enclosure inside.
If I had to do it over again, I'd try to find a B with that extra level of convenience. We don't use our aisle shower,
and have to find shower facilities when on the road which isn't usually too big of a deal. Another issue is the engine
power is a bit low for the weight of our van as previously mentioned. Third, as we do a lot of driving in hilly terrain,
a better transmission/engine/braking combo system would be nice. It's adequate, but could be better considering the
added weight of the van fully loaded.
Good luck.
It's a chore to search, call, see, and then decide, but when you find "the one" it'll be worth it.
