1600 lbs is too close for comfort. The Max Trailer weight assumes a truck that is empty except for fuel and a 154 lb driver. The weight of any passengers, any gear in the truck and even the trailer hitch is not included, so has to be subtracted from the truck's tow capacity.
We recommend that the trailer's GVWR be used as its estimated weight. The Dry Weight is a fiction and doesn't even include propane in the tanks (about 60 lbs). It also does not include any options installed, even factory options. It's a generic weight for the base model and your particular trailer will almost certainly weigh more, probably anywhere from 100-300 lbs more.
You also need to be concerned about the pin weight (weight that rests on the hitch and carried almost solely by the truck's rear axle. On that size trailer it is likely to be 20% of the actual trailer weight or something like 2500 lbs. Make sure the truck's rear axle GAWR is up to that much weight - a busted axle or spring is no fun.
Sooner or later most everybody ends up with the trailer loaded near its max and it is not wise to assume anything less. We also usually recommend a 10% safety margin on tow capacity, but that is not a major concern on a 3/4 ton diesel truck like yours.
Will you be fulltiming or just vacationing? Fulltimers generally exceed 1600 lbs, but vacation use may not. Depends on YOU and what you feel you have to carry to enjoy life. Bikes, golf clubs, canned and bottled beverages, etc. add weight FAST! You will be amazed when you weigh the rig after three months of travel.
