One thing that has improved since the Flying Cloud was made in 1956, is the method by which to stabilize and level the the trailer when camping.  If you ever traveled or camped, you know what I mean.  The standard of the era was the Reese aluminum screw stands.  A pain to install, limited in height adjustment, and not able to actually level the trailer, plus with their small surface area, were subject to rocking - and then there was the matter of where to store them while traveling.   Not use anything?  Having the floor pitch around as you get in and out of the trailer is the result, not to mention spilled coffee or waking your partner up in the middle of the night with a mini-earthquake while you tip-toe to the bathroom.

Solution?  The heavy-duty steel scissor jacks designed for RV's.  They bolt on the frame with large lag screws, and can lift the trailer to level if necessary. They tuck up out of sight unless you look directly under the trailer, and while not as convenient as the multi-thousand dollar hydraulic version in motorhomes, they  do run up and down quickly with a socket on the end of a cordless drill. I think Wally would have approved...
