Hey, I am very sorry I am just now responding, check the stickers in the driver's door for payload in particular, there are enormous swings in these numbers. If the numbers are all good my only concern would be power. My trailer weighs 14,000 and the DM handles it like a champ. I'm not very familiar with the gassers performance but I suspect you'd be ok just not sure if you headed into the mountains with the power loss at elevation.
