Purchase advice appreciated

There is a ton of information on this site and others that will address most of your questions. I was not sure what your "total" budget is, is it 50K plus the trade in or is it 50k total? If 50K total, you will have to go to a much older DP in the 38-40' neighborhood to make the numbers work. I am just now in the process of closing a deal on my first A. My wife and I shopped for 2 years, going to every show and multiple times to the same lots as their inventory fluctuates. We learned a lot doing that. I started out wanting a DP, and while I can afford it, I just did not want to shell out that amount of money. I also did not want to buy new and take the big hit on the appreciation. So I ended up going with a 35' gasser made by a quality manufacturer. The DPs are built better, and they can tow more, but the upper end gassers are lovely coaches and I am confident that my wife and I (not full timers) will be very comfortable in this rig. And we were over your 50K number BTW for a low mileage 2008. I think you will need to shop for a 2000 or earlier coach if you want a 40' DP around $50K. Check out the PPL site to get some idea. Best wishes on your search.
