Congratulations, that's a beauty!
If I found a deal like that I'd bite in a heartbeat.
We're towing a 6K TT with an Expedition EL. I hope to get a smallish 5th wheel next, so will be looking at Super Duty's and the like as the time approaches.
I may go with the F-250 gasser as my short commute might make the PSD hard to live with.
