New to the forum, probably joined the wrong forum- but there is so much expertise here. I'm an old fart and enjoy twisting wrenches. I am in the process of buying either a std trans Xterra or Pathie. I want something to tow behind our new to us motor home. I've found a pretty good body and package of 2001 Xterra with a holed engine. Question to resident experts- am I limited (practically speaking) to replacing with another 3.3, or can one dream bigger with a 3.5 (with attending ECM and wiring problems). I don't want to hot rod the thing, just good torque and able to pull my small 16' fiberglass boat. From what I've read and understand, a standard transmission is the only way I can tow either of the mentioned vehicles. Any input would be welcome. Thanks.
