I'm hoping our FJ will pull ours OK until I can save some money up for a new Tundra, since my 1st Gen Tacoma is too small and modified for the task.
In preperation I've added an 18k GVW stacked plate aux. transmission cooler, Air Lift 1000 rear air bags w/ onboard compressor, Prodigy 3 brake controller w/ 7 prong plug, load range-E 10-ply Cooper S/T Maxx tires, Ultra Gauge, Andersen No-Sway WD hitch and a 4Ucam wireless rear camera. If it will get us through half of next summer camping within 4 hrs from home we'll be good.
I also picked up a Sherline LM 1000 tongue weight scale so I can be sure to not overload the FJ's rated capacity.
I "think" it will do a decent job temporarily.............of course I could always throw in a few safe sways on the way home from picking it up to seal the deal early on the new Tundra
