I agree with JamieGeek....
I dont have your model but for the most part they are all the same.
Plan to spend about 2 hours looking it over inside and out (During the Day time so you can see everything). Look for roof leaks, Delamination of the side walls, Windows, other water leaks inside RV and Make sure Every single thing works (frig, Heater, Genny, Roof AC, MB Dash AC, Elec outlets, lights, Tires... ETC).
Take it for a drive and makes sure it feels Okay to you. THen offer them about 5K + LESS than the asking price. Most will take it or neg. with you. Walk away if they dont.... lots of New and Used RV's on the market IMO.
Lots of little things all the time. If you read this forum regularly you will learn a ton like I did. Im still having fun so its been worth it to me.
