first, fly across the country to buy a 22 year old truck and then drive it home like you don't give a fuck:
Then, buy an overpriced cargo trailer, because the market is FUCKED and 5 year old used trailers are the same price as new!
THEN, realize you'll need to install a 7 pin connector and brake controller, because this trailer has ELECTROMAGICAL brakes! But before that, test the existing 4 pin connector, because your new one will use that to feed four of the seven pins for your new one!
Oops, go fuck yourself! The california/colorado heat and sun has BAKED that mother fucker into brittle pieces of shit!
