Sorry about your wife, but it's good that you're still planning to travel. I find that the 5th is far easier than a TT for just about everything, especially hooking and unhooking. Although I don't have it, the automatic leveling is supposed to have a "memory" when unhitching so hitching backup again is a one button operation and there's no weight bars, snap-up brackets to hook up. You can even get one of those notched tailgates and not have to worry about lowering the tailgate. Heck, with all the doo-dads the new 5th's have, you would only need to bend down to hook-up the drain hose, and all of it can be easily done by one person.
I can easily see the hitch and kingpin, so hooking up is very simple to do. I simply lower the tailgate, drive under, the hitch latches automatically, hook-up the electrical line and safety break-away cable, then hit the retract button and raise the tailgate. I have to also manually raise the landing pads since I don't have auto-levelers, but the entire operation is simple and with electric stabilizer jacks the operation is so easy on the body!
