We have the same unit and love it. Had some minor problems up front but they were corrected under warranty by our dealer. Hereís my issues:
If you have the Sanicon system, check the hose compartment for screws. Our had a screw that held the skirting sticking in it.
Check the wiring of the slide motor above the drivers side rear tire. Ours was only taped to the bottom of the trailer and fell down to rub on the tire.
Check all the propane connections to make sure they are tight.
Well, a big one. Check the brakes af the end of the year we. Ours and others had the pads break down and the replaced them all. If your brakes sound like sandpaper when applied, you have problems.
Good luck with the trailer.
