Ok...so to jump in so you "geeks" don't feel too lonely here,
Liam and I live (with our 2 cats) in a 1974, 21 foot Tioga built on a Dodge Sportsman chassis, no slides, no office, no bedroom even. We sleep over the cab, our "office" is the dinette (which is definitely NOT the most comfortable seating ever designed), and the catbox resides (semi-permanently) in the shower.
What we love about it:
It is completely paid for - we gave $2800 cash for it!
Almost anything that can go/has gone wrong with it, we can fix ourselves (exceptions: replacing the black water tank, and coming over the mountains in NM & AZ, when we started having engine trouble that we couldn't ID and thought was the fuel pump, we had a shop diagnose...turned out to be clogged mufflers!!! (never heard of a muffler clogging before, only catalytic converters))
It looks and performs a whole lot better than most rigs we've seen that were 10-15 years newer.
Things we're not too happy with:
We're still (4 years in) working to gradually reclaim it from the Brady Bunch. The dark pseudo-wood paneling got painted before we hit the road, the dark orange carpet was the next to go (replaced with light-colored vinyl tile), then we replaced all the cabinet and closet doors (and the bathroom door) that were kinda ugly and falling apart with new ones we made ourselves. Now we are in the process of getting rid of the orange-plaid curtains. Later, we will replace all of the orange-plaid cushions. (Yes, we are starving artists-can't afford to do everything at once).
The 2 cats take up the entire house! Seriously! We cannot move without sitting or stepping on a cat.
We've had to get very creative with figuring out where/how to store all our stuff in it.
We'll probably eventually trade up, but who knows how many years it will be before we do.
