5th wheel vs Bumper Pull!~ help a newbie

Used to have a smaller Jayco 5th (26.5 RLS) towed with my Heavy Duty F-150. Now pull a Grand Design 34 ft. travel trailer (2670MK), with the same truck. Both are about equal in sq. feet inside, layout, etc. Loaded weights are in the same range. The fifth generally pulled better - no wiggle in the truck, tracked on turns better, withstood strong winds better. But the difference is not extreme. After 14,500 mi on the fifth, I averaged 10.5 mpg. After 4,500 on the TT, I average about 8.5 (!) I found it harder to back the fifth as the response seems to be non-linear as opposed to the TT. Most of the noted differences seem to be due to a lot more trailer further behind the truck for the TT than the 5th. Longer tail to wag the dog, so to speak. The "tow behind" length also makes it harder to find campsites - I can't wedge in to some I used to get the fifth into. The TT needed much more attention to weight and balance - too little tongue weight, and sway happens. Not something I had to sort out on the 5th. But - 5ths require a LOT more payload capacity for the truck. I was right at max payload with the 5th, and when it had to be replaced later versions had gained 4-500 lbs in pin weight, which put me well over, hence the change to a TT. Be careful - my F-150 has payload above what many commonly found f-250's have! If you have the payload, you lose most of the use of the truck bed for stuff with the 5th. For a 5th, the big limit is truck payload capacity. For a TT, the first limit is the amount the truck receiver can carry, then the payload of the truck. All trucks can pull far more weight than they can carry. I find it much easier hitching the TT than the 5th - but a big part of that is the specific hitches used on either. Others will report exactly the opposite.
But if I was shopping for a truck and an RV at the same time again, I'd first find an RV (5th or TT) that I really, really liked and then get a truck that not only could handle it, but was "oversized" to some extent to allow for changes in the future. Is one decisively better than the other? Nope - they are different, and so each have their own strong and weak points.
