Anyone make a mistake buying first MH ?

No mistakes....learning experiences! First mh was a 24' Minnie..liked it fine but eventually it became too small. Moved up to a '97 Winnebago 33RQ Brave with couch slide/Ford 460. Had 6,200 miles on it and the owner had lived in it 'on the job' for 6 months. Don't know that I'd buy another motorhome that someone had lived in full time as we had to replace the toilet, furnace and converter. Other than that it was a great mh (we drove it across the U.S. twice) but it was underpowered...got down to 25 mph. going up some long hills towing a Honda CRV. Recently traded it in on another Brave (2003,34D) with the Vortec 8.1 engine, 5 speed Allison transmission on the Workhorse W20 chassis. Love the floor plan, added power and the transmission. Have 2 concerns however, the 19.5" Michelin XRV tires that I've read a LOT about on this forum and the suspension. Workhorse knows they have had problems in the past as they've put Bilsteins on the 2004's. Have talked with our Workhorse service person and requested that Workhorse put on Bilstein shocks all the way around as I had them installed on the '97 Brave and it made a BIG, wonderful difference. Three different service techs drove it (not on any rough roads you can bet) and couldn't find a problem. That mh bounced up and down going over some rolling roads enough that we were yelling..."Whoa there Big Girl" and "Yahoo". It even 'bottomed out' on our last trip so something isn't right. Guess I'll have to go in again and complain some more. Will probably take off the front tires and replace them with another tire I'll feel more comfortable with as these Michelin XRV's sound like a nightmare just waiting to happen. So, again, no BIG mistakes, just learning experiences!
Happy and safe travels.
