I recently bought a small travel trailer and I have decided it is time to upgrade my suspension. I do not rock crawl or do anything crazy. I mostly do overlanding while camping, trails on rivers and beaches, fire roads etc...
My trailer is the
NuCamp Tag XL Boondock is about 1450lbs dry, 1700lbs loaded. The tongue weight is probably around 220lbs. It has trailer brakes, and I have a redarc controller.
While parked I get a little sag in the rear which gives me a reverse rake. This also causes my hitch to be a little lower than ideal, which gives my trailer a slight forward rake.
While driving the trailer is very light so it does not give me many issues. I do notice its weigh going up hill. I will sometimes get a front to rear bounce when going over higher speed bumps. No sway
While pulling the trailer the cargo are of my 4Runner typically has nothing in it besides 3 dogs (170lbs total) and a cooler for drinks. I do have Rago cargo window storage, and a raingler attic loaded with a few things, and a 10" sub (probably around 50lbs total)
2015 SR5 4WD no 3rd row, no cargo tray, LFD 3/4 roof rack

Bump Stops ?
Air bags ?
My questions:
With the new rear springs Im hoping there will be less sag in the rear. Which will also keep my trailer more level (less tongue weight). Which I assume would help with the front to rear bounce as well. I assume the slightly stiffer springs would help with the bounce in general as well.
Do I really need airbags or
Timbren SES for such a light trailer?
My worry with the Timbrens is that it would limit travel. Im not too worried about airbags, and I already have a compressor under the hood.
My next question would be the rear bumpstops. I saw a few people that used the
Lexus / 4th gen air suspension bump stops. These are cheap and seem to suit a 1.5" lift. The other option is Durobumbs but the
DBR35 which are for under 2" lifts, but they are more expensive and only available from a few vendors.
What do you think is the best option for the rear?
