So go ahead and do it, then come back and ask if there is an ointment to treat your white knuckles.
I think your math is wrong. If your that much in love with your 1500, buy a smaller TT - one within it's limits. Airbags and shocks don't increase payload.
Good luck getting this thing home as your tongue weight will be well over 1000 lbs - how did you calculate that? Did you check the weight limit on the receiver?
You hauling your family in that setup, or are they driving in a separate vehicle? I wouldn't put my family in that one.
Good luck - you seem to be in need of it.
