Need to make a correction:
Fla Statues; Definitions 320.01(1)(b).5 The “private motor coach,” which is a vehicular unit which does not exceed the length, width, and height limitations provided in s. 316.515(9), is built on a
self-propelled bus type chassis having no fewer than three load-bearing axles, and is primarily designed to provide temporary living quarters for recreational, camping, or travel use.
Fla Statue 316.515 9a (9) BUSES AND PRIVATE MOTOR COACHES.–
(a) Anything in this chapter to the contrary notwithstanding, no bus or private motor coach may exceed a length of 50 feet, ........
Takeaway, max length with Bus/Motor coach w three load bearing axles is 50', not 45' I noted earlier.
Guess that is my path for a solution here,
Back to the drawing board.
Now I am wondering what the overall effeciency gain might be by adding aero devices less the extra energy to carry and roll another lightly load axle due to added weight, rolling resistance, and air drag.
It never ends.
