Both of those dealers suck. Chesaco sucks more than Pete's, but not by much. If you absolutely need to use a dealer for service which is not warranty related, which it sounds like the issue is not due to wind damage, drive further north to Keystone RV Mega over the line in Greencastle PA. At least you'll only have to wait a month or two there if you're lucky.
"Is this standard for the RV industry?"
Yes. They're busy prepping and pushing new sales out the door while your rig rots away on some back lot. They probably let your battery/s discharge to nothing and killed them too in the process, and hope it did not develop a leak while sitting because they could care less about that also. If I was to guess at the percentage of RV dealer that suck in this regard I would say more than 80%, 99% if it happens to be a Camping World.
