I'm guessing, you are extending the ball/receiver. The farther you extend the ball the more leverage the tongue weight has to squat the rear suspension, but extending the trailer tongue reduces the hitch weight, having less effect to squat the truck, also the longer the tongue, shorter the distance from the ball to the rear axle the better the trailer will follow, the better it will track on the highway.
From the look of the trailer hitch, reworking it, getting the trailer to ride level, extending it to get the room you need to fit the plan you have would make the most sense.
Thanks for the info. My brain had the math backwards on trailer balance.
I had been looking for a trailer like this for a few months and finally found this one. Bringing it home included a long road trip that included a 3 day exhausting road trip. Except for the total weight of the trailer, all the details can be workable.
The trailer has a pintle hitch and when I got to the Pintle Hitch store they only had one that fit a 2" receiver, which was a straight one (their website showed a lot of options and they did not answer their phones) so i had no options, my plan was to buy an adjustable height hitch attachment but only one the straight arm was available. I had no choice drag the trailer home with what I had, now I can figure it out.
I am starting a project on my truck to update steering because older Dodges have a limited lifespan, and possibly suspension that will include a 2-3" lift. Until the trailer is built and the suspension is done I am going with what I got, it tows fine for now.
The guy I bought it from built it himself, it is crazy heavy duty. I will ask him to help design or add a longer tongue onto it. With a total of 10 storage units with the likelihood I add a rear hitch means I have 10-11 options to adjust the balance of the whole unit after an extension is figured out and a camper is added.
