That's a cool rig. I believe it's 5500 lbs dry. add water, propane tanks, batteries, beer, groceries and junk. Plus 800 lbs of bodies firewood and junk in the bed of the truck your adden up fast. You'll be ok. I did that combination for 2 years but with a 150 rated the same. Just keep it slow and safe. Hills may need a down shift. I usto take steep hills in 2nd at 45-50. Overall you'll be ok in my opinion. Loaded you should be around the 80% mark for what the truck is rated for. I'd go for it. Thats a cool trailer. Your next post should be what to look for when buying a used trailer. I'd hate to see it full of hidden mold from an old leak etc. Have fun and welcome to the forum.
