Definitely the right choice for a bumper pull, but it depends on how you are going to use it. We have a 33ft bumper pull, no slide out 2020 Keystone Springdale and love it. We lived in it for 2 years easy, and it was good, our 3 kids with the double bunks had no issues. We also go and travel around with it. I would look for one that has all the cheap outlets and plastic fixtures swapped out. Make sure you get on the roof, and look. Ask them how many times they have resealed the roof joints....the right answer is every year even if it doesnt leak. Make sure the black tank has a san T hose hookup, this will help keep the black tank fairly clean and once a month of doing that seems to work. Make sure they show you that the hot water heater, fridge, stove, AC, oven, and vent fans all work on electric and propane if they are dual energy. We have two propane tanks, definitely worth it in my opinion.
I would try to find one that has the weight distributing hitch that comes with it AND a fresh battery. Whichever one you get, go to every corner of the RV, and step on the floor to find soft spots. Its not the end of the world in my opinion, but it may be that there was a leak at some point and other damage may be hidden. A backup cam on the back of the RV is a nice to have but not a must. If the RV has slide outs, make sure you get the stabilizer jack that is supposed to help keep it stable. Same goes for the RV, if it has the stock stabilizers you will want to upgrade to something better. I also highly recommend a dehumidifer for the RV, here in Louisiana it has been a life saver.
Lastly, to re emphasize the roof sealing process. There are two types of roofs, you get sealant A for roof A, sealant b for roof b. I cant remember what the two types are, but listen it doesnt matter what the seller or even an RV dealership tells you. Every single year on a sunny day, you will pull, scrape, and peel the roof sealant out of the seams. You will then, re apply the proper sealant to the same seam, ensuring uniform application. This is something you should never skip or else you will get water in the walls of your RV. It rains more here in Louisiana than any other state in the continental US, this is what hundreds of RV dealers told us and in Washington State the same thing from the RV dealer in Tacoma. If I was going to neglect everything else, this would be the one thing that I did actually do.
