GVWR - unpublished? Seems like you can figure it out using UVW + CCC = 9858. If you calculate the tongue weight at 12%, its 1183.
Subtracting your available payload leaves you 408 lbs. Now subtract the weight of people, WDH, cargo, etc, and your way over your TV's GVWR.
So people say, I'm never going to put in the max cargo weight. Well, then cut it in half and your still over the limit. Also, the published dry - UVW in this case, weight does not include weight of propane or battery. Lop off another 100 lbs.
Another revelation - max tow capacity is calculated by pulling a flat trailer with weights on it. Pulling a high walled TT down the road pushing the wind out of the way is just not the same.
If you want to use your TV, then you seriously need to downsize your TT.
Can you even use a WDH on this vehicle? Wheelbase is also a consideration for such a long TT.
Here is some more reading for you on the subject.
Learn To RV - What can I tow?I faced your situation when starting out - forced myself to downsize the TT. I wouldn't put my family in your TV with the TT you have planned hooked up to it - no way.
