Chevrolet Silverado 2500HD Forum : “what do you need to add to get more towing capacity”

You should look for a bigger truck.  The 2500 is not suitable for this type of load.

You can handle it with a 2500HD no problem. Make sure you get the diesel. Airbags in the rear would also help
keep it level, and invest in a good electronic brake controller.

We have a 2001 2500HD and we pull our bobcat trailer and that full loaded is about 14000 lbs so you shouldn't have a problem pulling your fifth wheel, but it helps if you get a performance chip which increases the horse power and putting a exhaust system to let the engine breath more.

get a programmer if u want more towning cap. and that should be all u need depending on what u are trying to haul

unless the truck you are looking to buy is the 6.0L v8 the you should have no problems towing 12k......I work for a chevy dealership and the numbers i am showing you came straight out of the general motors tow ratings

that truck is definately under rated for a 12000 lbs 5th wheel.your truck should always be over rated.just cause you might get away with it doesent mean its right.its not safe.the air bags and programing and extra horspower are great but it still doesent change the rating of the truck.if you run with the holding tanks empty and dont take much firewood youd probable be close to your rating but i would say buy a lighter 5er.always leave a margin for error.and its best if its on the good side.the last thing you need while traveling is be worried and uptide about you rig.makes for a real long haul.just my 2 cents.
