I'm personally interested in solar myself for the Travel Trailer I just bought back in November... However i keep seeing you use the words "before I take delivery". This might be of interest to you, my true story... I live in Florida so things might be different here, or might depend on the dealership contract. But it's food for thought, never the less... Somewhere in my 1000s of documents (felt like 1000s anyways) Was this paper that in very fine print said by even signing the paperwork... I acknowledged I was taking delivery...Even though the travel trailer was being delivered by the dealership to my home in a few weeks. Needless to say, the dealership damaged my rv while bringing it to me home... When i talked to the dealership about the damages, they informed me... that also in very fine print, in the contact. It stated they were not responsible for any damages while the rv was in there care at anytime for any reason.. I sincerely hope that this does not apply to you... but it did apply to me... and the more questions I asked, the more they were unwilling to honor anything... including my very expensive top of the line extended warranty I purchased. He actually dared me to use the extended warranty... saying it's not uncommon for simple fixes to take several months to fix... and when I simply asked to speak with the owner of the company... I was told to leave several times or they were calling the cops on me... Now keep in mind... I'm recording this entire conversation for my own personal reasons with my phone.. and I was extremely careful to be calm cool and collected at all times... So i can only imagine how they would of reacted if i had actually been a smart ass... it's best not to pissed off the dealership if it can be avoided... believe me... I sincerely tried because I had already been told no one will do warranty work on your rv but the actual dealership that sold it to you... even though my coverage was supposed to be national wide.... Other dealerships will typically not work on rv's that they didn't sell you...
