A
fully fueled Cessna 172 (All Metal Aircraft) weighs about 1700 pounds. ... 240 pounds of that is fuel. A Piper J-3 as in the picture weighs ..(All Fabric) ..what..? Havn't looked it up but my
guess would be around 850 pounds.
A late model 4x4 Toyota Tacoma Pickup weighs about 4000 pounds. I'm guessing a snowmobile weighs about 450 pounds....add the rider. Just throwing out some numbers for reference........for those that are interested in details.

NB
PS: I would really like to hear from the J-3 Pilot as to the all up weight of the J-3.
