Yes Jim, I pull my 1999
Casita 16 SD with a 2001 Toyota Tacoma 4X4 extra cab with V6 and 5 speed manual trans. Just got back from a 3500 mile trip the Moab and the Tacoma did a fine job. I had to cross the divide on Trail Ridge Road as I-70 was closed due to flood damage but it was not a big problem. I will admit that the V6 was a little short on power at elevations over 10,000 feet but that is what the gear box is for. I never had any problem doing the speed limit on any of the mountain passes and those included Red Mountain and Monarch in Colorado.
