I am looking at a 260 that is ~350 miles from my home lake. We have a 2017 Yukon XL - 5.3L V8 with 3.42 rear end upgrade. Standard Class. Our hitch is only 5,000 lbs and needs to be upgraded, but with that upgrade, will we be able to comfortably tow the 260 on a custom aluminum I-Beam tandem axle trailer? I don't want us to be on the ragged edge of disaster for a trip that long. Thanks in advance!
