With the WDH set up correctly, factoring in that a portion of the tongue weight is sent back to the trailer axles, it is realistic to use a the rated 865 as hitch weight as a ballpark, with a bit of that sent back to the trailer. Maybe a bit more when loaded
So 1400lbs - 800 tongue leaves you with 600lbs for people and stuff. Put the cargo in the trailer, and people only in the truck and you should have adequate payload for you and yours. (EDIT - Not only that but the springs are the low rated item on your truck, the axles and suspension are designed and rated for much more, it's the springs that dictate your vehicles GAWR, and GVWR).
But that's all a guess, but folks who tow full time have a vastly different bent as far as running heavy / daily driver compromise. you certainly are no over by much, and if set up correctly should be plenty safe. Being a few pounds heavy because of lower rated springs is not the end of the world.
Some pretty whacko tongue weight assumptions and lack of real world experience with regards to what ends up on the truck axles being posted, as usual.
"IF" the OP only loads 1100# into the trailer and most folks with a trailer that size load considerably more (we would routinely load 1200# into a 22' TT),... then he will have 1138# of TW (based upon 13% which is considered about right). "IF" that WDH transfers 20% of that weight back to the trailers axels (a very big IF), then he has 911# of TW + another 100 for the WDH + 800# of passengers he now has 1800#+ with only 1400# of payload. Do the math, he is at least, bare minimum, 400# (about 30%) over his payload and probably much more than that.
The above numbers assume minimal loading, empty tanks all around but that is just not how it works in the real world. Dump stations can be out of order or just backed up to the point that waiting an hour isn't an option so now add another 600 to 700# to the equation. Often you are probably headed downhill, now at 500 to 600# over your TV's GVWR....can you say white knuckle ride?
The OP gave us his numbers and asked for input and he can take or leave it but the numbers do not change. Nothing "Whacko" about the the TW numbers quoted here. The best advice here has been load it up and get to the scales and the numbers will be glaringly apparent but the bottom line is that to run hundreds of pounds in excess of your trucks rated GVWR is foolish, dangerous and illegal. :S
