I went through a similar dilemma after buying out camper. Looked at extending the trailer tongue, but that only solves it for that one trailer. Still lightly on the table, but not likely.
My trailer is 6100 lbs so a whole lot less, but not many more options.
I bought a torklist extension for $320 nearly new.
I'm waiting for a torklift hitch to show up on craigslist. Then I'll make the change.
There seems to be a lot more torklift takeoffs for Fords around here than for Chevy's. You might find the same.
I'd also look into overload springs and a swaybar.
Keep an eye on craiglist and facebook marketplace and piece it together.
