While our present TC does not have a slide, it's long (11'4") and very heavy (dry shipping weight as printed on the document from Lance was 3872 lbs) and THIS TC has traveled on our 2004.5 Chevy 2500HD D/A CC LB 4X4 truck for just under 50,000 miles now. GM HD pickups are all indentical with the only difference between the 2500HD, 3500HD SRW, and the 3500HD DRW being spring capacity, tire size/capacity, Shock piston diameter, and number of wheels. Model badging doesn't handle any weight at all!
The big Lance Legend ordered new has every option available including the 3400 watt propane generator and two 30lb propane tanks but we didn't order the solar panels (new option then) as we much rather use a 1500 watt inverter and 3 large Group 31 deep cycle batteries with 225 minute reserve each. 2 of the batteries are in the driver's side bed ahead of the rear wheel well and clear the TC lower side by approx 2". Access to batteries is thru the lower door Lance TC's have. #2 gauge welder wire couples the 2 batteries to the one in the TC battery compartment above with the disconnect switch and 2 no 2 gauge eyed WW pigtails I put in going thru the bottom of the compartment and well sealed. The 80 amp marine slow blow fused on each end cable with a lighted remote toggle on/off switch at the bottom of the instrument panel in the truck to trip the 80 amp relay under the hood off if wanted. It's the re-charge cable. 675 minutes of 23 amp DC draw reserve! Yes, it's a lot of added weight but simply outstanding for silent 1500 watt AC anywhere. That's silent power for the coffeemaker, toaster, microwave, TV, puter, etc in the morning anywhere anytime! RV battery re-charging is done thru the #2 welder cables attached to the frame under the truck from the bed batteries to the dual alternators on the diesel engine or when the TC generator is run. Re-charging is very fast and efficient!
Our truck, ordered new in 2004 has dual alternators, Rhino sprayed in bed liner, added Air-Lift 5,000 lb airbags, full length special made running boards, 265 "E" Michelins in leu of the 245's, Tow Beast 2-1/2 HD receiver, Rancho 9000XL adjustable shocks, four-3/4" grade 8 in the bed bolts remove the welded together 5th wheel hitch base for a clean bed when the TC goes on, etc. Truck handles, rides, and drives excellent.
Before this 11'4" TC was being used after being stored inside for 11 years, we had an optioned out 9'6" Lance TC on the truck. We purchased the 2 new TC's originally as we had a 3500 DRW and a 2500 truck but sold the dually because my wife's back couldn't handle the stiff jolting ride. 18 operations later, she now could handle it but our present truck enhanced handles the big Lance just fine!
BTW, on the rear of either Lance TC was a 2' X 7" welded steel square 1-1/4" x 1/8" tube frame with a walmanized 1/2" plywood deck covered with thick indoor/outdoor carpet with a steel and plywood storage box 18" X 24" X 16" high with a sun shield Formica hinged tabletop we carry hookup power cords, hoses, leveling ramps, our Coleman propane grill, etc in. Our 2150 LB 16.5 King Troller fancy boat on it's trailer or our 6' X 12' X 6' high inside vee nosed enclosed trailer GVWR of 3500 lbs attached to the porch's rear. I do limit the trailer's tongue weight to 350 lbs or less always as I have a 500 lb cap scale and load items into either trailer to control tongue weight.
All in all, our total load on our truck is as high or much higher than carrying just a TC with a slide! The truck now has close to 150,000 miles on it and has only been used for RVing since new. Not one repair needed or done to the truck yet and just started on the 3rd set of tires this summer including the original Bridgestone 245's that showed steel belts in way under 40,000 miles.
If we'd buy a new truck I'd have to do all this stuff to it also and besides, our truck is finally just broken in now! At 71-1/2 years old now this truck will likely outlast us anyway!
