I have a Tacoma 6 cylinder and it pulls my 20 Seafari very well but I think the 4 cylinder will do an OK job. As you say, it's rated for 3500# and my old 4 cyl. Ford Ranger was only rated for 1600# and still did the job adequately for VERY short distances, the only problem it had was coming up the ramp. You won't have that problem with the 4 cyl. Tacoma, it's more powerful, however, I think that for longer distances or highway use the 6 cyl will be more economical than the 4 cyl since the engine won't be working as hard. I can go about 200 miles on a tank of gas with my 6 cyl. Good luck with your choice.
