Anyone make a mistake buying first MH ?

1st motorhome 27 years ago was a 21 ft 1976 Western Commander Class C with single soft wide tires in the rear. It was on a Dodge 1 ton van chassis with the 360 engine. Lots of power when I added headers and a 4 barrel carb. Worked well for me, spouse 3 small rug rats and the family dog. Strange things like a single small house battery, about a 30 gallon single holding tank, wooden framing, aluminum siding etc. We had a lot of fun for a couple of years and very few problems. 15 years later my current wife and I purchased an '88 27ft Pace Arrow Eleganza. Looked great but the windows leaked like a sieve. The dealer had it parked inside and nice and dry when we picked it up and headed for the beach in a driving Pacific rainstorm. Apparently the prior owner had kept a dog who used the carpet for his private privy and when the carpet got wet, the smell was so bad we ended up ripping out the carpet and depositing it in the dumpster at the campground. WE WUZ HAD in no uncertain terms. Negotiations with the dealer and my attourney eventually resulted in replacement of the carpet and sealing of the windows but we started looking immediately for another rig. Settled on a new '94 31' bounder on P30 Chassis. Enjoyed 4 trouble free years and 48,000 miles before selling when my tag end female child got heavily involved in high school and club sports. With her graduation from college and retirement rapidly approaching we bought a low mileage well equipped '94 32ft Adventurer (11000 miles) about 18 months ago. This is the one MH purchase I really wish I had done differently. The rig is in great condition with many options - two airs, 5500 generator, 2 big solar panels, jacks, camera, Bilsteins, steer safe and full Banks with K&N Filter. Runs great with lots of power and no problems. We got it at a cheap price but we are not satisfied with it and have been shopping new gas or used late model diesels at least 36' with dual slides as we plan to spend 4 to 6 months a year on the road. We were looking at new Southwinds when the salesman showed us a new 40' Alfa the other day. d**n him anyway! We've been dreaming ever since but it's way out of our price range. ($100K or less) Should have gone with the bigger rig and been done with it before. As it stands now, we will have to negotiate a trade or sell the Winne. Either way, I expect to get beat up financially. Would I do it again? Probably as we like the RV lifestyle. We are really shopping for the next purchase as I want it to be the last and expect to run it at least 10 years. It is only a real mistake if you fail to learn from it and the only time to really regret something is if you intend on doing it again and don't learn anything.
