Thanks to all of you for the ideas. I'm much clearer now on what will and won't work. Here are my needs and perameters: We don't have really bad winters here in Tn but I do think it's worth it to spend a few hundred on a decent furnace, most likely a Suburban NT20. I'm about to rebuild my interior and am trying to maximize interior space by building in what I need and moving anything I can under the floor. I'm hoping to get my propane tank under the van somewhere, as well as 2 batteries on Ford's frame mounted boxes. I have a large rack on the back already which holds Rubbermaid bins and bikes, and I'm out of space there. Also, I don't want to kick around a portable heater anymore, and I don't really want to spend as much as a true SMB setup (frame mounted tank with hole in van, etc.) I can weld up a frame to hold the tank in the space I mentioned under the rear of the van, and I know I will still have to crawl under there to turn the valve on or off, but it won't get used very often, and I doubt I'll have to remove it more than once a year to refill.
I have a great local propane guy who sells all kinds of parts, tanks, etc. who I have not yet been to see, so I think I can plumb this all in and build it rather inexpensively, except for the tank itself and the furnace. Oh, BTW, I might do a single/double burner stove or stove/sink combo, if I can make it fit.
These translucent new fangled tanks are really cool, but I don't want to pay $200 for one. I found these at Camping World, pretty great prices.

I'm wondering if a 10 lb. would be big enough because I could probably mount it standing or slanted and not have an issue, also they are DOT approved, etc.
What do you guys think? How many pounds are the typical small RV/SMB frame mounted tanks?
Thanks
