I picked up a lovely 94 Minnie Winnie last year with just under 60K miles for just under $10,000
Needed new tires on the rear axle, fixed a charger solenoid for the house battery, replaced black water valve, propane detector, propane regulator and front brakes. NO DELAM!!
Prior owner flushed radiator and serviced transmission and rear-end! The only thing that sucks is one of the ABS tone gears is bent so my ABS does not work and they no longer make the part :(
Been a rock solid rig and I would not hesitate to full time in it, if I was in your situation (single no kids and my giant Newfoundland dog).
Anyway your budget is reasonable and if you are ok with the space inside, do it! I went from a 31' Class A and the greatest thing I love is being able to fit in the 'off the beaten path' campgrounds. Even ones that say no RV's are no problem... I do miss the basement storage of the class A tho, can't have everything I guess ;)
