Older Class C with 350 Chevy Engine?

As newbies, we bought a heavy old 79 Delta Chevy powered "nightmarish" 23-footer with carburetor engine, points, inadequate engine cooling, and lacking in power at high altitudes,struggled pulling grades, inadequate brakes,RV generator and old roof AC needed overhaul, dash AC didn't work, engine heat through floor and dog house were excessive, furnace needed replacement. We payed too much and invested another $8K in overhauls, replacements and upgrades the first year. Never did repair the leaky roof and get rid of mold smell.Racing fans often sit on roof with lawn chairs causing leaky roof. Unless your prospective rig was maintained very well, is cheap enough, and you have the time, skills and tools , work space and money to spend, I would recommend saving your money and buying a much newer rig. Whatever you buy, for safety sake, it will need six new $300 tires right away if tires are 4 or more years old by date codes regardless of appearance or tread depth.
