I am still not clear on some things; perhaps you can clear them up for me.
1) You bought the camper directly from Prime Time? or from a local dealer who sells Prime Time trailers?
2) You said the camper was hit in transit. This is a critical piece of the puzzle that can not be trivialized.
Even the cracked shower stall could have been a direct result of that impact. The frames are made to bear the weight of the camper at it's maximum gross weight. Period.
Getting hit in an accident will far exceed the rated stress the structure is designed to withstand. Damage can extend far beyond the point of impact and most claims adjusters will be unfamiliar with the damage even a minor accident can cause. Roof leaks, misaligned slides, broken cabinets, cracked plumbing fixtures and fittings, and damaged axle mounts can be overlooked if the adjuster is not aware of the hidden damage an accident can cause.
Today's cars can be "totaled" in a minor accident if any frame damage is suspected. Same with travel trailers.
You said it is all FR's fault. How is an accident occurring during delivery FR's fault?
How is your local dealer involved in this process?
Did they suggest rejecting the camper and demanding a new one?
Did they offer that? (IMO they certainly should have with damage like you described)
How can a "rebuild" be better than new? This is dealer speak for "Please take this POS wreck because I have a waiting list for deliveries and you will mess that up if you want a new one."
I am truly sorry for your troubles.
Is your dealer standing with you "against the manufacturer" or are they blaming FR and tossing you to the wolves?
