Our Starcraft was 7'6", the Escape 5.0 TA at 7'4" feels wider, it's plenty for us but I would imagine you'll have to see one and judge for yourself.
I find hooking up easier then the bumper pull, unlike Donna I can reach the hitch lock and pin without a ladder. I also have an in bed 7 pin connector so I don't have to go under the loft to access the one on the back of the truck. If you can reach the middle of the bed standing on the ground you'll be the same.
The ride is nicer with a FW, no hitch jostling back and forth, at least with the Patriot hitch, it's a good solid connection. I'm comparing this to our 20' Starcraft.
Backing up is different, it turns slower then the bumper pull.
You obviously lose some or most of your truck bed with the hitch depending on the bed length. I've got an 8' bed, plenty of room for my stuff but I can no longer use the truck cap so the canoe stays home, at least so far.
If you need to use the truck as a truck you need to remove the hitch. It's pretty heavy to tote around and even after removal you have the rails in place. It's doable but a bit of a hassle. Some of us use a tonneau cover, it helps to keep things out of sight when you're disconnected.
The FW (fifth wheel) is taller to clean and access the roof.
You have a couple stairs to climb to get to the bed, it bothers some with knee issues.
Separate bed area works out great for us.
My F150 (3.5L EB) has no problems with the FW, still learning how to handle down hills in the Rockies. Overheated the front brakes last fall, replaced them this spring.
