I have this setup now . A 4k max load for the trailer, 500lb tongue wt empty and 900 lbs tongue wt with the 4 wheeler on the trailer. Still in the tow wt range and gvwr but high on the tongue wt. I use a Andersen wt distribution hitch and am going with airbags to keep the truck level. I had a 3/4 ton truck (f250 6.7 diesel) and was over trucked for all conditions and decided to down size to the 1/2 ton with the 3.0. One trip out west each year will be at max load GVWR. All the other use with and without the trailer is far from max limit. Hope this helps
Happy new Year
