You are still missing the payload number for the truck, this is the number that is important in most cases. Payload number means the amount of weight the truck can carry, this is all the people, cargo, coolers, foods, pets and the weight of the trailer that is carried by the truck. In your case the only known number is the 2210# hitch weight (dry number). The dry weight number is not an actual number, this number will change when you add cargo to the trailer. This number theoretically could increase or decrease depending on trailer loading. Adding all the weight to the back of the trailer will decrease tongue weight/pin weight and vice versa for the adding it to the front of the trailer.
Again not being the weight police but did you look at the brochure posted? The brochure states that the payload for your truck is 2512#, so if you minus the cry weight number (2512-2210) = 312 lbs leftover. So as it sits now you have 300 lbs for people, cargo, coolers, pets, snack ect. You can load the trailer with weight in the back, your trike at 1400 lbs will take some weight off the pin/hitch freeing up some more payload.
If you load it smartly, then get it weighed and make adjustments in loading according to the actual weights you should be just fine, you will possibly be pushing the limit but you should be able to get it in spec with smart loading.
