So, I lied. I don't actually own an Xterra, yet. We would like to buy a used Xterra for our son when he turns 16, but we will also be using it to tow our 2400 lb pop up camper, with a tongue weight of 500lbs. I have tried to find out which year, which trim package, which engine, which transmission, and whether a 4WD or 2WD would be better. And our selection is limited. But I keep getting mixed information and figured who would know better than the actual drivers of Xterras. So, please help me. I know all about the GVWR, tongue weight, yada, yada, but again I get mixed info, mostly about the factory tow package. We will be doing most of our driving in the Ozarks, which means lots of steep winding hills. MUST it already be equipped with the factory tow package or will an after market work? Will a V6 be sufficient or must we look for a v8? Will a manual or automatic (my son prefers manual) work better? 4WD or 2WD? So many options.
