Another issue may be the trailer license plate etc... It is sometimes a RED FLAG when law enforcement finds a trailer with a license tags from one state and the truck license from another state... They will pull you over to check it out...
I would definitely have paperwork on board showing you are the owner of this unit etc... Bill of Sale...etc...
Our state requires safety inspection stickers.... Not sure What Texas or IDAHO has... having expired safety inspection sticker is obviously another RED FLAG for law enforcement..
