RE: Yee-Ha Above Illustrated Above. The stubby pipe accomodates cargo module addition (s) added to the frame when the needs arise.
Yee-Ha frames are generally considered a welded frame and their cubic volume is something to be rationalized. These frames are typically 6 ft in length to meet shipping size constraints.

Stand-n-Pee Raft Frame
Yee-Has can ship UPS.
Unlike the original all welded Yee-Ha RaftFrames, these are sub-assembled to fit in a reasonably sized package that allows parcel shipping. The side panels feature welded aluminum deckplate with mechanical tee fittings.
Cat chassis can be configured by adding the option package.
