We have a new to us 2005 3400 RL we got just a few months ago. Our first 5th wheel. We bought a used one because I wanted to see how many trees and stop signs I would take out before dropping 60 or 70 grand on a new one.
She's not as pretty as yours. In fact, she has a distant beauty. The farther away the better.
We purchased a 2011 3400 RL and really like it. It lives so much better than our motor home for the 7 months in Florida. I'm in the process of changing a few things. The first was to correct the lack of a/c in the toilet. It was easy as the duct work is only inches away in the ceiling.
Enjoy your new unit!
We bought our First Keystone and first Montana in Feb 2018 it is a 2018 3121RL we love it but last rig we will buy since we got it New and got everything we wanted. We love camping but the costs and depreciation is not fun, but we do love the Montana great rig.... Good luck to you with yours & Happy Camping
