Nice trailer, I checked it out online. I use to have a Jayco 32BHDS that was very similar. We really liked the U shaped dinette, the double entry bedroom with the TV that flipped between the rooms and the bathroom entry door. You'll be able to comfortably sleep more people on that trailer than I can on my 43ft toy hauler.
It does not have the Schwintek In-wall slides that you may have read about on this forum. It also doesn't have cable slides. I think it's a through-frame slide, but it could be an above-floor slide. You'll need to look underneath to tell.
You can view the different slide systems on the Lippert site @ Product List
My Jayco had through-frame slides, the maintenance is minimal, maybe an annual lubrication. The important thing with any slide system is that you know how to manually override if it fails. The through-frame slides will have a manual crank for the motor, usually on the opposing side of the trailer from the slide. On my Jayco you had to remove a trap door in the under belly to access. I had a Torque were it stuck out of the frame on the other side of the trailer and you could crank it with the tool for the stabilizer jacks.
The only time I had a problem with the slide on my Jayco was when I opened it off level in a bar ditch. It would not retract, but after just a few turns on the manual override, I heard it pop back on track and was able to pull it in the rest of the way with the 12V motor.
Enjoy your new trailer... Spring will be here soon!!!
