Expect your gas mileage to be really bad. That's just the nature of towing with a first gen Xterra. I towed a Ford Escape on a tow dolly for about 70 miles with my 01 non-SC Xterra. Granted, not near as far as you'll be going, but my experience was it took forever to get up to highway speed, but once at highway speed it did better than I thought it would maintaining the speed on level ground. This is obviously in tow mode. When I say highway speed, I mean 65 max. I think I was between 55 and 60 most of the time. Like the others have said, take your time and enjoy the scenery..Correctly balancing the load in the trailer is very important.
If you're going from Denver to Texas it's downhill most of the way so there is that, lol.
