Go back or not.

I had my whole roof redone after an accident.  We picked up the rv from a service dealer who was reccommended by the manufacturer.  We noticed that there might have been a problem with the solar panels and the batteries being depleted.  We called amd informed them and they said that we could have it checked close to home and let them know.  We didn't.  Two years later we are going to go on a trip again (had not used it) and in preparing, we notice that there are short circuit problems with the generator and A/C, shore power and the A/C, and the solar paas seem to be draining the batteries as well as they are not charging them.  We reached out to the company that rebuilt tue roof and told us to bring it.  My question (after two years), should I make the four hour trip to leave it and pick it up again at a later time, trusting that they are going to be honest about any mistakes made, or should I find a local service dealer to independently to look it over?  Will the service dealer who rebuilt it accept the local opinion?  With they wash their hands either way?  The panels were new Go Power.  The A\C did work both with the generator and shore power before tye accident.   I am accepting all opinions.  Thank you
