Welcome the forum.
At a budget of $85K you have a RV World of choices.
Seasoned RV'ers know that RV markups are generally in the 40% range, and realize they should be able to negotiate a $100K true MSRP, not the dealer made up look alike , rig for under $70K! Patience is your friend, and don't take your check book or credit cards I to any dealerships.
Don't forget to take into consideration what your tow vehicle is (or will be) and the true combined gross combined weight it can handle, not what,, the RV salesman tells you with "you're good to go" BS. There are more experienced folks who tow on the forum that can enlighten you on that.
The more information you provide what you are looking at, Mfg, Specific Model and Model number, year, and your tow vehicle, the more help you'll get from forum experts.
