Ram 2500 coil vs Ram 3500 leaf: squat test

Test RV is a 40' Silverback 5er. It has 4 slide outs, one over the hitch. It has a 15,500# GVWR. Loaded as it was, the 5ers pin weight is likely over 2500#.



His truck is a 2014 Ram 3500 SRW, Cummins, 4x4, crew cab, short bed equipped with the factory leaf springs.

Mine is a 2014 Ram 2500, Hemi, 4x4, crew cab, short bed equipped with the factory rear coil springs.

Neither truck has any after market rear suspension gizmos, and are completely stock. Both are under 5000 miles on the odometer. Both have the exact same OEM wheels and tires.

Keep in mind the driveway slopes down to the street, then the street slopes up at the end of his driveway. There are no sidewalks in the neighborhood.

Here are the pics.

RAM 3500 SRW:



Unloaded height - 42 3/4"


Loaded height - 40 1/4"


Overall view hitched up



RAM 2500:



Unloaded height - 43 1/4"



Loaded height - 40 3/4"



Overall view hitched up



So both sagged about 2.5". I didn't have time to do a test drive, but we might do that in the future. That is a huge 5er.

    Both trucks were WAY OVERLOADED. Even though i drive a Dodge Ram QC, 2500 HD, Cummins powered, I would never venture out on the highway with either trucks. Unless i'am seeing these photos wrong, you are nose high with both trucks. I would really go for a dually, for safety reasons. You are in the MDT type of trailer hauling.


    People need to read the OP's first post and look at the photos.. the way the street/sidewalk angle the rear axle is lower than the front and trailer axles.

    The 2500 is at it's limit for GVW and GCW, but this isn't a tow test... as the title implies it was a squat test.

    The 3500 isn't overloaded, but it's a BIG trailer for a SRW.

    WAY OVERLOADED is a bit extreme, considering the actual pickup ratings.

    Way to much camper for either truck, did noone notice how low in the back both were.


    Did you not read the OP's post? The driveway slopes down and up, making the rear look lower than it is based on street/driveway angle.

    They appear to have 5" or more of sag, but only have 2.5" based on the numbers....
  • Interesting stuff!
    However, one thing that doesn't come into play is how much the suspension moves and handles the weight bouncing down the road.
    The static tests are good info though as it doesn't look like either one is squatting too much.

  • most importantly it looks like you have plenty of bed clearance
  • I, for one, would love to hear more about the results of your experiments. Keep 'em coming! :)
  • Was the trailer loaded? A 15,500# GVWR trailer should have a pin weight over 3000#, not 2500#.

    My advice is a dually for that trailer, not a SRW.
