From Truck Camper to 5er and now back to a Truck Camper!

With the 225/70R19.5 tires, you probably have close to 4000 lbs capacity per wheel even thought the Rickson rims are rated at 5000 lbs. My 811 could push the rear axle weight past 7000 lbs and when I towed my enclosed trailer was closer to 8000 lbs. I went 245's to get more tire capacity and some reserve so I did not have to worry about weight. I'm sure your boats are lighter than my 8000 lb enclosed trailer, but you may want to run the front and rear axles across a closed weigh station to get some real numbers.
