53 or 48? What else?

Wheels that turn and lights that work.... couldn't resist.... LOL

 

Weight is the biggest thing it seems but that comes with it's own drawbacks. Probably the best thing is a 53' all aluminum with a sliding rear axle. This would get you legal for both Commiefornia and Canada. There is maybe 2k difference between the 48' and 53' You have a pretty light truck so I would say once you get all your gear and fill the tanks you would be right around 32k full of fuel. With a 53 you could have an 11' upper deck and still have room on the lower deck for a container.

 

My 2016 T680 fully fueled with an empty 53' combination flatbed weighs in at 31160 with all gear and me in the drivers seat.
If that helps

 

You should be able to legal 50,000lbs. I kept my truck/trailer tare at 30,000 or less

 

I don't see any reason to waste money on a 53 when you can have up to 4 feet rear over hang on a 48 without a permit but 0 on a 53

 

If it were me I would just buy a 48, I can't justify the extra weight of a 53. You are allowed up to 4 feet rear over hang on a 48 but none on a 53 without a permit besides that how much space do you have from back of the sleeper to your first drive
