    I’ve got an 05 srt-10 quad cab. Considering a camper and possibly small trailer to pull the viper. The truck is completely stock. 65k miles and seems to be fairly well maintained (although I’m sure previous owners ran the shit out of it).

    Here is my questions: Any other quad owners out there that are or have pulled anything like this? What did you do to the stock rear end/suspension so it doesn’t squat on the rear tires?

    I know these muscle trucks aren’t made like 4wd trucks for heavy haul jobs, but something in the 7500lb or less weight range is all I’m looking to do. Thanks in advance for the feedback!

    You could possibly add some rear air bags, but I wouldn't tow much over 6000. I found this on the internet:

    Can the Ram SRT-10 Viper Truck Tow an RV?
    RV weights can range between 1,000 and 9,000 pounds or even more. The SRT-10 can tow an average RV weighing about 5,200 pounds. Therefore, although it can’t pull some of the larger and heavier RVs, the Viper can pull most RVs.

    So without comparing specific spring pack numbers and option codes, as far as I know the SRT QC leaf springs are the same as a regular 1500 QC. 2005 SRT QC has a max tow of 7500 lbs with a payload of a little over 1000 lbs with 22" wheels, 4sp auto & 4.56 gears. This jives well with the 2005 specs for a 5.7 1500 QC, which are 1650 lb payload & 7850 lb tow capacity with 3.92 gears, 5sp auto & 20" wheels. The same 1500 QC with 17" wheels goes up to a max trailer load of 8900 lbs. The wheel size (and thereby weight) is an important factor. The heaviest thing I've ever towed was a 2004 Liberty (about 4100 lbs) on a steel dual axle flatbed trailer (2000 lbs) and it was fine, though the TN mountains got a little hairy.... Just remember with the camper that you need to factor in cargo, both in the truck and in the trailer.

    When I bought mine in 2019, a previous owner had installed some racing rear springs. It was only two leafs, and whenever I hit a bump, the ass end would bottom out. So I went back to OEM springs, no more bottoming out.

    I don’t tow with mine, but the rear helper bags will help with your truck not sagging and will level out your truck when towing. Adding a rear sway bar when towing will also help out with stability when towing. I have both rear help bags, rear sway bar and definitely help out with stability/comfort.

    The rear air bags work great ! have used these in different trucks many times , they give you the option to add more air or less pending the load etc . You can also air them down to retain the stock ride when not loaded or towing etc .
    I install mine using seperate air valves for left and right , because sometimes you need a pound of air more in one more then the other for level etc .

    I used a Hotchkis sway bar, which are discontinued now but there is other options.

    Your only options are a belltech rear sway bar part #5555 or a OEM factory rear sway bar from a RC SRT10.
