I tow with a 2015 F150 Super cab, 2.7L Ecoboost. The truck has a payload capacity of 1641 lbs of which the wife, myself and stuff we carry in the truck comes to about 500 lbs. After 100 lbs for the WDH we have around 1000 lbs available for tongue weight. My hitch rating is 1100/11,000 lbs with a WDH. Our loaded trailer comes in at 5168 lbs (scale weight) give or take 100-200 lbs depending upon trip length. The tongue weight runs from about 670 lbs to just under 700 lbs again depending upon trip loading. The truck has a maximum tow rating of 7600 lbs and while our truck with us would allow that high of a rating I put the practical maximum around 5.5K lbs. This allows the truck to have some headroom and not struggle in the mountains (I hit 6% grades on some of our trips). If I were to go to a heavier loaded trailer weight than we have now I would upgrade to the 3.5L Ecoboost, max tow and heavy duty payload packages.
The first thing to keep in mind the 3700 lb dry weight is not the real empty weight of the trailer you will drive off the dealer lot. The dry weight does not include the propane tanks or battery nor any optional equipment weights. Each full propane tank will add about 37 lbs and the battery around 50 lbs. Add in all your stuff and it is common for a trailer to be 1K lbs or more over the dry weight.
You should have a sticker on the driver's side door pillar that tells you the available payload for your vehicle. It will say something like the maximum weight of all passengers and cargo cannot exceed nnnn
lbs. From this you need to subtract the weight of all passengers, their personal effects and cargo that will be carried in the vehicle. Subtract another 100 lbs for the WDH and the remainder is what you have available to carry the trailer tongue weight.
You will also need to compare the tongue weight to the ratings on your hitch. I don't know enough about GM labeling to tell you where to look. On Ford trucks there is a sticker or metal stamp on the hitch receiver with the ratings. If your truck only has a maximum tow capacity of 5300 lbs I suspect you will not be able to handle the tongue weight of a loaded 2106FBS. The only way to know is to find the receiver rating.
You also need to be concerned with the Gross Combined Weight Rating which is the total maximum weight of the loaded vehicle and trailer. Lastly is the Gross Axle Weight Rating. This is the maximum weight that the axle can carry and is the combination of all weight on top of or behind the axle. Usually GAWR is not a problem if you are within the payload rating. If any weight is exceeded the trailer is too heavy.
We use to tow a different trailer with a 2001 Explorer. It was the 4.0L V6 with a 4.10 rear end and an oversized transmission cooler. It had a max tow rating of 5740 lbs. I added an after market hitch receiver as it could only bumper pull 200/2K lbs. We found we needed to stay with trailers under 4K lbs loaded and and ended up with one that came in loaded at about 3300 lbs and tongue of around 420 lbs. Its dry weight, which included propane, was 2650 lbs.
