Cthns,
You see lots of overloaded 250's towing Montana and similar size 5ers.
Airbags will help you ride level but don't change your weight ratings or help you stop. Bummer, you need a bigger truck. Been there and been as surprised and dismayed as you when I found these forum topics.
Your biggest risk exposure is overloading the rear tires and maybe the rims. If you keep the truck, definitely fix this!
Good luck.

We just got a 2012 Ford F250 diesel crew cab short bed. Then bought a 2012 Montana 3150 RL. With a pull rite sliding hitch. Husband wants to add extra fuel tanks. When we tried to calculate the weight measurements to see if we could add the tanks, we find that our king pin weight is more than the rated payload. The Montana Gross weight (shipping weight + carry weight) is 14,160 lbs. hitch weight 2160 lbs. the truck GVWR is 10,000 lbs. the cargo weight is not suppose to exceed 1,661 lbs. We see lots of F250s towing Montana and similar size 5ers. What are we doing wrong trying to figure out the weights??
Thank you.
Well not pulling a Montana, but I am pulling a 5er with a GVWR of 12,000#, currently loaded to just a little over 11,000# with about 2,200# on the pin.
I tow this package with an 01 2500 Ram with a camper package, while the stated GVWR of the truck is 8,800# the total GAWR is 11,284#, I run with a GVW of 9,700# while towing our 5er, Holly Cow Batman the bumper must be dragging on the pavement!!!
Well this is a picture of our rig ready for the road,
No Air Bags, No air shocks, No modifications at all to the factory suspension.
