I towed my 21' 2600lb camping trailer. Phoenix to Flagstaff AZ and back . It was a better ride than my 2020 5.0 f150.
I was pleasantly impressed.
Lost half my MPG overall.
Same situation as pulling with my truck
This is the exact set up you stated
It seems a little to squishy in the turns coming down hill at 65 to 75 MPH.(leans alot) not sure how it. Compares to stock as I bought it with the lift.
Just took a 300 mile trip woth a 3000lb camper(loaded) dropped the rear about 3 inches but drive great...
I live in Arizona. I pulled it off with my fingers and 90% of the adhesive came with it. A soft cloth with hot water and the rest came of in about 30 seconds
$3,000.00 . Upgrade on the 1958 from cloth seats to leather ventilated seats. That was with the purchase of the new vehichle. So take the number with a grain of salt.
