Congratz on the Amerilite. We have had one for a few seasons now and love it.
At a max of 3500 lbs you should be ok with the tow limit. You need to find the trucks payload too. That's how much the truck can carry and everything in it including the tongue weight is included.
I agree that you need a receiver hitch. You will need a weight distribution hitch with sway control.
You don't have a lot of carrying capacity in the trailer so I suggest filling the water tank at the campground and emptying the tanks before you leave. That removes 240 lbs from the towing and weight off the tongue as well.
