Hello Burley, yeah I agree that we are in a similar situation however, you may have a little more weight to play with than me! The dry weight of the 189 is 3288 lbs and the actual weight that is labeled on the yellow door sticker is 3778 lbs and that is not including the extra junk. All said and done I think we will be about 4200 lbs and the tow capacity of the xterra is 5000 lbs which doesn't leave much. But I think one of the most important investments is a good weight distribution hitch and an anti-sway bar. Our setup cost about $300. This really helped handle the weight much better than I expected. The 189 does push the V6 engine to work pretty good, but it took the weight much better than I thought especially in the high Clovis NM winds! The xterra made it to 60 mph well and could maintained nicely however, Clovis does not offer me hills to test it out. If circumstances were different I would buy a nice truck but I think the xterra does well. We just have to keep in mind we are getting to our limits and that we need to take it slow. Let me know what you decide!
