F150 and a Camper

I have a northern lite on a chev 1500 camper dry weight is 1450, loaded on the deck is about 1000 over weight, added 2 leaf springs, and e rated tires rides well but I drove professionally all my life use caution I still think you need at least a 3/4 ton truck but this is how I bought it and just added the mods plan on a new truck in the future, in Ontario Canada I called the ministry of transportation they said all is fine just keep receipts in the truck as proof of upgrades an insurance said I was OK
