I didnt burn a tranny on that trip... I did prior to that in the TN mountains. If there is very very little traffic, I tend to go faster. Knoxville to 1 hour west of Fort Worth took me 15 hours including a flat that I had to change myself and get to the tire shop.
The worst towing experience I had is when I picked it up when I bought it at Pier 57 and drove it home in a snowstorm... that BLEW!!!
and it is an XL Denali

No it was 39.3 when you put these props on.....

Towing my Velocity 260 home from New Orleans with a 2004 Explorer 90+ mph

Because of the gearing and tranny, the truck cannot pull the boat under 70 in OD. It can carry the OD easily over 70 or 75 as the rpm are high enough to get on the engine's torque curve. On 70 mph limit highways we routinely tow 80mph.

35 Mistress 10,000+#'s MI to NJ: first 50 miles did not break 60mph. Next 800 miles would not go over 74.5mph (or under 65mph up/down/left/right LOL ) w/2001 Suburban 2500 w/Vortech8100

Excursion wiht the SR behind (7500#) 60-65 MPH is comfortable. I can do a lot more but I like to relax and cruise.

One time, and one time only. 2000 Expedition, same boat, 92 MPH. When I realized how fast I was going, I backed off. Too my surprise it had more left. Not stock suspension. It was in pursuit of a drunk that passed out and turned hard left into my trailer as I passed him.....at 60 MPH. He got caught. He had drugs. He went to jail. His bosses down south were not happy he got busted at 9AM on a Saturday morning "transporting" their product. His car pretty trashed, my trailer got a dented fender and broke the stick-on reflector.

Funny part was, they had no cause to search his car until he threw the beer can out the window as they pulled him over (after 30 minutes of us and another guy chasing him with no law in sight)...instead of the bag of weed on the passenger seat.

my little 18' powerplay behind my 2000 3/4 chevy. Mid 80's about fast as i have towed it. Ask wette vette I went by him on the way to hardy dam a few years back

I may not have the fastest boat, or the coolest tow vehicle, and I know it is bad to say, but I guarantee you I have won this thread. and it cost me 5 transmissions.

'97 Chevy crew cab dually, 454, auto

the ford trans. does not like interstate 44 with 16k load on propane,nos,160hp chip,180hp injectors, and no wastegate.

Bigyellowcat,

My brother raced cars prefessionally and pulled a 35ft enclosed goose neck trailer with an older Chevy big block dually and it would pull well over 100 on flat land. Those are the ultimate pull trucks short of the commercial rigs.
