Anyone make a mistake buying first MH ?

First mistake...Now retired and with fortunate life possessed of more $ than smarts bought a 40'DP. Way too big to enjoy. Second mistake...Trusted PPL as broker fell in love with a truly beautiful and loaded but older coach and relied on PPL's vaunted check-thru ($235.00) and then stupidly relied on PPL's recommendation of INDEPENDENT (ha ha) inspector to COMPLETELY, THOROUGHLY inspect all systems. Off we went...two innocents...then in short order and over $10,000 and many repairs later our "perfect coach" was perfect. Unfortunately and yes our fault the coach was still too big...too old...oh yeah, did I mention that our expert salesman, expert PPL and expert inspector somehow failed to notice that this coach had been in one of those famous Texas floods. My very first service/repair tech at a Cummins dealer told me that in literally two minutes.
