porpoising

[hazmat456]

Ram came with a factory option air ride system. Which rear suspension do you have?
Add on air bags do definitely help, as will increasing the tongue weight. I have my fresh water tank in front, under the bed and it tows much better when full. If your fresh water tank is behind the trailer axle, I suggest towing it near empty, if in front of the axle tow full.

I am also a bit light on the tongue weight at 740lbs when loaded at a 6,600lb TT weight, which may also be contributing to the problem.

Have a 24sabwe & had many similar problems.... UNTILLLLL
I did as recommended on this forum.

Weigh the TV & TT, post the numbers here.

When done we now tow with partial, empty, or full tanks (as long as we're below GW.)

We were over the 15% (22%) which seemed not too bad @ the time since it "looked level"
Pressures were all ok but we got rid of "stuff" & moved necessary to the pickup bed, which meant getting rid of more stuff.

Get your weights as you use it, including fuel & people.
