5th wheel with short bed - a little worried

[Focker]

Mine is 23'.

I haven't experienced any porpoising with this truck or my previous truck, towing this trailer.

I have a hunch it's just that stretch of road hopefully

Regarding porpoising or bucking:
Insure the trailer sits level when hooked up to your truck.
Insure there is proper wongue weight in your 5th wheel. Shhot for 15% of trailer weight
Have someone ride in the rear seat, rear window open and listen for clunkning from the pin and hitch fighting each other, could be caused by too little tongue weight
If you have air bags, try reducing the air in the bags, too much air can cause bucking.

good luck and let us know what you discover.

Towed it about 100mi road trip, just got back, and it seems to just be that stretch of highway that I live on. Once I got off that it felt much better. Like I said before I get some bounce in the truck with no trailer at a certain speed, so I think the waves in that particular stretch matches perfectly to my wheel base.

I just did 100 miles round trip and I couldn't be more impressed with diesel power! It was effortless... Easily pulled hills and maintained 70mph.

Yeah I was very impressed as well. I had hills with lots of turns and pulling up them was effortless, but I was most impressed with how the truck acted going down the hills and how the transmission and exhaust brake worked together to maintain 55mph going down hill, barely had to even touch the brake and when I did I just tapped it and the exhaust brake kicked on again. Very impressed.
