RAM - squat test (pt 2) Hemi vs Cummins
PART 1 here
OK, so SKG and I did better (and more) measurements tonight when we both had more time. We also did a test drive, mpg test (quick and unscientific) and 0-60 runs with each truck. I have video of the towing (filmed by the passenger in each case), but that is still being uploaded. So I will update that later when the videos are up.
As far as the squat re-testing goes, we spent a little more time and took some better measurements this time. Check part 1 for a good description of the RV, but it's a 40' Silverback by Cedar Creek 5er with 4 slides. It has a 15,500# GVWR and likely ~2700 to 3000# hitch weight.
We measured each in the same spot on the street in front of SKG's house hitched and unhitched, and the space before the bump stop would make contact on each truck.
RAM 2500 6.4L Hemi (with rear coils)
Unloaded, 42.5":
Loaded, 39.8":
Total sag, 2.7"
Space between jounce bumper and axle perch (before suspension bottoms out) when RV is hitched up, 1.8"
Overall view** Keep in mind, my 5er hitch is set too high for his RV and the airbag pin gizmo he has on there, so the RV was a bit nose high when hitched to the Silver 2500 Hemi (my truck, SKG's RV).
2014 RAM 3500 SRW (rear leaf springs)
Unloaded, 42.25"
Loaded, 40.25"
Total sag, 2"
Space between jounce bumper and axle tube (before suspension bottoms out) when RV is hitched up, 2.75" (angle is bad for camera, but it was just under 3" by eye)
Overall view at same spot on highway:
That's all the static testing covered.
In part 3, I'll add the videos, and add the 0-60, mpg, and handling feel results..... you might be surprised :)
