If you can live with only 400lbs in your truck, that includes driver and passenger and anything in the bed or cab, then you will be just inside your payload rating. After that you have to consider controlling sway.
Can your truck do it? Most likely, but if you want to avoid white knuckle driving on the highway with wind or big trucks passing, you definetely need to look into a hensely or propride 3p hitch. Any conventional WD hitch with friction sway control is going to be a gamble.
If you want a trailer that big, but don't want to drive a 3/4 ton or larger truck the 80% or more of the rest of the time you own your truck, than the $3K it costs for hensley or propride is well worth it.
