I had a question about towing. I have a 2005 GMC Envoy SLE 2WD 4.2L 3.42 rear with trailering package. It has 107xxx miles and all maintenance is up-to-date. I'm doing a one-way move when I leave the Navy. Would it be OK to tow a 5x8 U-haul trailer about 400 miles without installing an aux trans cooler or any other additional equipment? I plan on leaving the trans in 3rd the entire time and following the owner's manual for not exceeding 50mph while towing. Any help is appreciated.

The place where I work is a uhaul dealer. I ran the combo through the system and it liked it. It's a pretty good system taking into account all the weights of the truck and trailer. I guessing you already talked to uhaul though....

I6, 3.73 gear ratio here. All that really helps is maximum towing capacity, and getting up to and maintaining speed. I went 55 most of the way until the trip was taking all day and night, and went 70 for the last hour of the trip maybe. 600+ miles in late August, so not exactly the coolest time of the year to help augment vehicle cooling.
Highest the temp gauge ever went was 1, rarely 2 past the top mark. 15MPG hauling a 6x12 that was jam-packed full; even had a 1930s dental chair in there that was like 300-400 pounds (I bent a dolly trying to get it moved). Hauled like a champ, and I drove for a good 15-16 hours, except the one-hour nap I attempted about 2/3 the way through. Other than that, only stops were at gas stations, 3-4 stops that took 10-15 minutes each.
If hauling is going to become a regular thing for you, a trans cooler may be of definite interest for you. For a rare or one-time deal, you should be just fine just following the manual
