This is my Talon on a 14' trailer (7" longer than a P1K). Since it was my first SxS, I had no idea where I was headed with the hobby so I went a little longer than minimum (if you have the room to store it, you won't be sorry).
Loaded for travel. I get by with a single axle but I'm right up against the 3500 lb. axle rating when fully loaded.
I had to add holes to the ramp holding straps to move it back far enough to reduce my tongue weight with a full load of fuel. Since I didn't know what I needed, I added 4 holes but cut 2 off later, one at a time. As the Prez said above, controlling tongue weight might be a problem with a shorter trailer. I also didn't know that I'd be adding a bed extender/spare carrier.
