Can Our F350 Carry a Lance 1191 Safely?

The dealer has said that if the truck is properly equipped with 2000 suspension increase, proper tie downs, sway bars and such that we will be fine. The local spring company will place a sticker on the door of the truck indicating that the cargo capacity has been increased, once the suspension upgrades are done.

What an interesting comment. Would Ford agree with the dealer that some spring and suspension modifications would increase the payload of the truck and thereby the gross weight rating and an aftermarket sticker supercedes the manufacturers placarded values? Are they going to increase your braking capability as well to accommodate the heavier truck weights? I think your dealer needs to check his facts and you should check with the spring company to see what they really put on that sticker. Springs won't increase the axle, wheel or tire ratings. After owning three campers, the last one on a one ton crew dually that still needed suspension modifications, I would add about 1000 pounds to the camper brochure weights as a good estimate. And then if you tow a trailer, add the tongue weight to that as well.

You will be over your truck's gross weight but how much is acceptable is a decision only you can make. However, never go over the axle, wheel or tire ratings. And remember the truck's brakes need to stop the whole load, unlike fifth wheels and travel trailers that have their own brakes to stop as well.
