Newbie looking to live on the road for a year! suggestions?

It says that cargo and passengers should never exceed 1352lbs

My girlfriend and i together weigh 400lbs (i account for more lbs of those than her!). My motorcycle weights 450lbs. and my dog weighs 50lbs. So that puts the total weight we add to the truck at 900.

***Also, we will only be in alaska during summer months. So yes, it will get cold, but it will not be alaska winter type cold.
