the A/C problem was because of the new bumper, and the line rubbing in a spot, my fault, and yes just a part of the trip.
Being retired and wanting to travel each summer, some more long trips (repeat of this one and Deadhorse added to it and Goosebay Labrador) and I hope 2-4 shorter ones each year, I just cant live with the 13.5mpg I got and I think I can expect gas prices to increase over the next 10-20 years. Now some of that is the weight I have on the GX470, so I will play with that and some of it is the way the GX moves air in the back, it hits the front of the trailer and cause a big drag. I am going to look at ways to modify the trailer so the air flows better. My 2013 JKUR, pulling the trailer, different box (5" shorter) and a little less weight (200lbs?)did around 16.5MPG for almost the same trip. My friend with a new JLUR pulling a teardrop did about 18mpg and a full loaded LX470 with a RTT did about 11.5mpg.
The other problem is the right front seat, its not the best for someone over 6' tall. After 3-4 hours, it becomes uncomfortable. Short people didn't seem to have a problem with the seat. This would be a little harder to fix, I think.
Over all the GX470 is a great truck, right now, I just dont believe its the one I want. Thinking maybe a new Tacoma in a few years. I do want to play a little more with the weight of the GX, a friend is bring his car scales over so that we can do some measurements and testing. So not really the GX problems, more what I want and my fit.
