This is what got me checking into weight for the front while hooked up. The door sticker lists the front GAWR as 5600 lbs.. It recommends front tire pressure at 65 psi. That may be the sole reason for this. My truck's front axle weight loaded as I previously stated is 5420 lbs.. So I'm almost at the maximum completely loaded with fuel and two people.
Ironically, I think I am probably worse off with my Work & Play TT. W&Ps have heavy hitch weights and I have my Equalizer 4-Way set really well and the truck sits close to what it is without the load. So I'm sure that has transferred more than enough weight to the front axle to exceed the front GVWR.
On a side note. I always keep the front tires at least 75 psi. Of course, the rears stay at 80 psi.
