Aunt & Uncle had a TT and the cousins used to invite us along occasionally. After we emigrated from the UK, we decided to try the hobby. Unfortunately we got a real turkey, an '85 Class C (26') with a carburated Ford 460. 6 mpg at sea level and 4.5 at altitude. Interior layout was bad too, aft/side bathroom with a standard size double bed in the back and a sleeper sofa. Sold after one season, then got a 2002 32' Class A with the V-10 a few years later.
We finally gave up the lifestyle after four years with the Class A. Lost a bunch of cash as a result of a very dodgy consignment deal, but in general, we're happy to have had the adventures but not sorry to have given it up.
When you have to dip into your IRA every time you use something, it's a sign you shouldn't be doing it!
