The truck - 2009 Tacoma Access Cab 4X4 SR5 2.7L 5 spd Standard (w/Hopkins agility brake controller)
The trailer - 2008 Palomino Real Lite 1202 (curb 2100, gross 3200, actual 2400 - 2600 with tank full)
Before buying this truck, I was surprised that many people believe you need a V6, V8 or a turbo diesel to tow. And the standard response to the question of what can a 4 cyl. tow "not much".
We towed approximately 250 miles this week, camper weight varied based on water load. As well the truck was well loaded with around 800# of junk, humans and whatnot.
Acceleration was good, shifting between 4000 - 4500, easily attaining 70 MPH into a 20 MPH headwind. I found 5th gear was doable, CC on, but the engine has an annoying rumble / drone @ 2500rpm. 4th gear and 3000 rpm was quiet and smooth. No sway, ride noticeably firmer, and choppier than normal.
Turning east the wind was pushing the truck around a little, but no more than usual. 5th gear doable only at almost WOT. 4th gear happy at 70, power to spare....
Merging and accelerating no problem, (and I'm very impatient). Accelerating to highway speed with other vehicles, no problem. 3rd gear and lots of RPM helped here. On occasion, pushed 3rd to 70mph.
Into some small hills and curves, required one gear lower than unloaded travel, still no problems...
Passed a couple vehicles, slower vehicles effortlessly in 4th. Had to run to redline in 3rd once on a tight pass. Pulled back in at 80. No sway, enough power.
Mileage was tough to gauge. I got 315 miles to a tank, 19.8 gal fill. I usually get 375ish....This tank included 2 hrs of off roading in 4L. Accelerating was mostly 3/4 throttle, 4000 RPM shifts. Not one stretch of road went more than 30 miles between stopping to turn, so lots of accelerating. Pushing headwind or crosswind both ways. (good luck eh?)
GCWR is 8000#
So after this short trip, I have no doubt that this truck could safely, and capably tow its 3500# rating. (If loaded correctly)
