Are you saying that the dealer accepted payment from Jayco in an amount that would pay for the installation of a new wall, which new wall Jayco sent the dealer. Then the dealer decided just to patch the problem, instead of installing the new wall and that the patch is cracked? Did the dealer keep the original large payment or refund the extra to Jayco?
If all the above is correct, did Jayco seem interested that the dealer accepted payment for a very big job but did a cheaper patch?
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
