I joined this forum just to reply, I have viewed for over a year though
I own a Stryker Toyhauler by Cruiser RV. I have many of the same issues you have. Mine was at a dealer for 30 days, nothing got fixed right. I then called multiple times to Cruiser warranty after about 10 calls and being blown off I had to get ugly and put a Lawyer on retainer...and let them know.
Finally it made a trip back to Indiana for 2 months and underwent some major repairs. First Cruiser does no repairs it went to DRV. I was like sweet they have their **** wired right....wrong.
The whole mess is pathetic. I have a $35k toyhauler that is the biggest piece you could imagine.
It came back 1/2 fixed, Lippert Chassis is a bunch of crooks and liers and Cruiser RV builds a cheap junk box.
Now out of warrranty and I own a clunker.
Good luck and I would not stop at a replacement I would not stop until I got out from under it.
