a few more tips
A lot of good comments in this forum. All I can add is
1- check all luggage compartment doors. We had a lot of issues with the latches not opening and closing correctly. Also check inside the bay for water leaks . The seals around the door are not the best.
2- run the microwave for at least 15 minutes. Ours kept shutting down after 10 minutes. Had to have it replaced.
3- Same with the stove. Once it reached the preset temperature, it would shut down completely.
4- check all the drawer latches. We had two broken ones. And while you're at it, check the drawer bottom panel. One of ours didnt fit and fell out.
5- check the electric door step. You dont want to hear any clicks and bangs. Ours quit after a short while.
6- Look for loose outside slide seals . Ours stuck to the slide side, pulling itself out of the track.
And finally, the biggest issue is to get repairs made in a timely manner. Our coach was at Buffalo RV for exactly two month, waiting for parts. I would never pay for a coach again on mere promises of having defects fixed. Have em fix it all before you pay.
