We tow a U Haul enclosed utility trailer a few times a year, to swap meets and car shows, with my Burb. One trip last year was across Houston, Texas and back, probably around 100 miles over the weekend. Burb had some load but most of our stock and fixtures were in the trailer, didn't get it scaled but I figure somewhere around 600 pounds of stuff plus whatever the single axle 5'x8' trailer weighs. The other show we go to in the spring is in Austin, Texas ,and last year we took the single axle trailer instead of the double axle one. Probably closer to 1500# in the trailer and 700# in the Burb cargo area, loaded properly with the heaviest stuff ahead of the axle. Around 400 miles round trip. In 2018-19, we towed a double axle trailer, with a ton of stock and fixtures, plus our personal gear and some merchandise in the Burb. We also went to and from Lafayette, Louisiana with a similar load and trailer in October 2018, with this Burb, about 450 miles round trip.
And weight doesn't include the 3 of us in the truck! This year we may take the crew cab with a trailer, and some stuff in the bed(tables and parts that won't mind getting damp). Depends on the weather and if both trucks are still behaving themselves....
Burb got 13-14mpg on the road, hauling; it'll be interesting to see if the big truck can do that too. Same engine....
First pic is after load-out in Austin, getting ready to head to the motel. Second is heading to the Houston swap meet, across town, third is getting ready to head up to Austin. Half ton Burb and notice it's only leveled! Towed great, both trips.
