This pretty much means that anything more that you load into your truck such as bikes, firewood, grill, tools, chairs, etc will bring you over gvwr. I wouldn't do it, that is just me.
I admire your for doing the research. If you decide to go this route, then make sure that you have the best WD hitch you can get. Make sure you buy it from a hitch dealer that knows how to adjust it properly. Most rv dealers dont. Final hitch adjustments need to be made when loaded ready for camping, not when you pull the trailer off of the dealer lot. The distribution dynamic changes significantly once all is loaded.
Also, your truck likely has p rated tires. This rating is not optimal for towing heavy loads and since you are at max, you may want to consider LT rated tire. A stiffer sidewall means more stable and less opt to sway. Oh yeah, watch the transmission temp, if you don't have a temp gauge then get one. Never allow trans temp to exceed 225 or so. What axles ratio do you have. If geared 3:55 or below, your transmission will likely run hot.
Good luck.
