Lance 1025 on 3/4 ton diesel Silverado

The payload is determined by the tires. Put two Nitto or Toyo tires rated at 3750@80 PSI and you have 7500 - 3000 (weight of your truck on the rear tires) or 4500 lbs. of load capacity in terms of the axle, wheel bearings, and tires.

If the camper weigh causes the truck to sag in the rear then for $500 you can add a set of SuperSprings that will take an hour to bolt in place. No different than the 3500 that has a second leaf pack on each side.

With a 4500 lb. maximum payload you can stay at 4,000 lbs. maximum with gear, food, water, etc. and go with a camper that has a true dry weight of 3,000 lbs. and there are many to choose from.

1000 lbs. may seem like a lot to allow for "extras" but the Lance weight does not include an AC, a second battery, a roof rack, generator, solar panels, or the weight of the fresh, gray, and black water tank fluids at about 8 lbs. per gallon. Add a generator and fuel or tow a trailer and add a heavier duty hitch and a stinger and it is easy to push the boundaries.

The other $3500 option is to get Rickman 19.5 rims and 19.5 tires at which point you have a rear load capacity of 8800 lbs. minus the weight of the truck. Not cheap but a better option in many ways than DRW.

Once you find out how heavy your truck is, you should have around 1800 lbs of payload left. Now the truck will carry a lot more than that but I also believe you are going to be over your load limit of your rear tires.

When I had my 2008 Chevy 3/4 ton diesel crew cab I added extra springs to the rear which let me add 800 lbs extra to the payload. This only cost about $200.00

You need to add at least 500 lbs to your 2600 camper weigh to go from dry weigh to wet.

I had my camper at a wet weigh of 3700 lbs on my 3/4 ton and I didn't like the thought of taking it on a long trip so I got a bigger truck. It looked fine and if I had only planned short trips I may have never did it.

You will beyond the capabilities of your truck. Your camper will be very close to 4000 lbs loaded lightly. Your diesel engine is a lot heavier than my gas 6.0 and I'm at my max load with a 3000 lb camper.

I have carried a lot more Lance TC on our '04.5 Chevy 2500 D/A CC LB 4X4 truck for over 70,000 miles now and it handles and rides great. Our Lance is 11'4" and weighs about a thousand pounds more than the 1025 you are thinking about. It's optioned out to the max including a 3400 watt built in propane generator amd 2 - 30 lb PP tanks. Alterations to the truck includes: airbags I inflate to approx 65psi, 265/75/16 "E" Michelin LTX tires on the OEM steel chrome plated wheels that came with 245 tires, 4 Rancho 9000X adjustable shocks. Better than the 3500 SRW suspension OEM capacity! That's it! Been on the cat scale twice so far loaded to travel and never been over GM's specs yet including the rear tire max capacity.

Tire capacity is usually the weak point and first to be over max limits and always should be at 80 psi. 19.5's will hit the torsion bar and you'll have to crank it down a lot so the tire doesn't rub in a turn. Rides terrible! They also add to tippyness when driving. A very expensive change to make! 2 I know have tried the 19'5s and went back to 265's when they found out the hard wallet thinning way and sold their 19.5 stuff.

You might be fine already. Assuming truck has E rated tires. Does your truck have the top overload spring? IMHO one does not have to run out and buy 19.5 rims and tires right away. What kind of rims do you have if Forged Aluminum those are strong. I have been impressed with the Nitto high load index tires. Nitto terra at 3750 lbs. at 80 psi or the Durra which has even more capacity at 3970 lbs. at 80 psi. I am on my second set and have hauled 2 heavier campers than 1025 for thousands of miles. I have added airbags, Helwig sway bar, add a leave springs to rear pack, and Bilstein shocks. I recently purchased a 1998 Lance 990 Legend 11' 3" model with a stated dry weight of 3259 Lbs.which I am sure is not accurate and have no problems hauling with my 2006 Dodge 2500 long bed 4x4 CTD loaded for a trip.

You will likely carry it fine, but you might be over the maximum weight on your rear tires. Moving up to 265 tires might do it, but certainly spending the money on the upgrades, 19.5 wheels and tires first, would make it feel a lot better. Your 2006 Duramax is one of the best around, so make it work for you.

You will be over-loaded in stock trim. But your (and my) AAM 11.5 rear axle has plenty of capacity, so if you're willing to seriously upgrade wheels, tires, and springs (which I did), and pack very light, you could/might probably manage. My FULLY loaded weight is ~3000lbs, which included a lot more than my empty camper.
