I'm also from BC----And no= Not to worried at all really.
I think that having the truck sitting level will help with that(Not A heat score)....Now if it was stock -that's the issue as you drive by. I've seen other trucks out there that should be pulled over.
My new trailers weight is 5600lbs and the tounge weight is around 700lbs, Polaris sportmans 500= around 800lbs and then the alum. boat and rack= around 300lbs.
Yeah i guess i'm over the weight limit...LOL
But fingers crossed it wont be an issue....So far it hasn't been, But i dont always haul the quad. But i've also had every thing mentioned above and my WR450F in the box also. Still wasn't an issue.
What drives be nuts out on the BC roads are the other RV drives going below the speed limit and they wont pull over...And i also notice a lot of people out there without trailer mirrors...Maybe they cant see me to move over..
