The trailer is a Keystone Premier Bullet 19FBPR. We were looking for 19' or less trailers as we dry camp in the forest. Total length is ~23' with a trailer weight of 4213lbs / GVWR of 6500lbs. One of the primary factors when buying the LR4 was the ability to tow.
In summary it is excellent, with 375hp/375ftlbs and weighing in at 5700 lbs, loaded at over 6000lbs and with a body on frame.
Keep in mind that my travels are mostly Colorado mountains, starting at 6200ft and going to 10/11K ft. I'm already down 15%-18% on power and rising.
I do not use an equilizer hitch. The LR4 air suspension works great to level the vehicle + trailer, along with the "
Trailer Stability Assist system that monitors the behavior of the trailer at speeds of 37 MPH or greater. If the trailer demonstrates swaying or oscillation, the system will use selective braking to help bring the trailer under control.". That combination works well through all the Colorado roads, to include
Red Mountain Pass. Without the equilizer it is easier to maneuver into tight spots.
I would think the LR4 would do fine with the 28' Outback. In reality it would probably be better than the F150.
Campsite was nice. We typically camp in the forest off forest service roads but decided to spend a few days at
Molas Lake between Silverton and Ouray. Elevation is 10,500ft. Campsites are tent/dry.
