It’s certainly safely doable ( at least with a Ram ;) ) with some upgrades to the truck.....though, you may potentially have liability issues if you are at fault in an accident! We’re running the Hensley, some stuff in the bed, and towing a 5er that grosses-out a little over 20K pounds, and occasionally tow doubles! But, to make it a safe tow rig.....upgrades are seriously recommended!
Though....the 1000pounds of fuel would likely be a “deal-breaker”! If you kept it at a more reasonable 500 pounds or less.....maybe! I also, would “not” consider.....unless the trailer has disk brakes! As earlier stated.....upgrades! memtb
