Need help finding place to set up car for towing Spokane .

"I will go after Camping World for the expenses occurred"

Does the agreement you signed with CW grant them the right to fix it? If it does and you don't, you won't be recovering anything.

"Dealer stated that when Camping World tied into the electrical wiring it caused the electrical command box to malfunction and cause"

That's "hearsay" and you can't use it. And what CW did has been changed by others to "fix" it. Best bet is to return to CW.
