Congrats. Picked up the 27BHS a couple of months ago. Love it.
Couple things about it:
Our bathroom sink had a loose fitting and it leaked a little when I pressurized the lines.
The outside fridge control is in a bad spot. It's on the back of the fridge next to the compressor. You have to access the control by opening the panel to the hot water bypass. That panel is on the rear of the storage bay under the lower bunk.
Check the seal around the door. The top corners had small holes in the sealant that I had to caulk up.
If you have the bumper grill, the mount was in a bad spot and I had to move it.
Have already spent hundreds on Amazon outfitting the trailer, and I think I'm almost there on "necessities."
