The main reason for the power tow discussion is for hangaring the aircraft with only a few INCHES clearance from each wingtip. In other words, light aircraft or not, if you have a slight incline into your hangar, or if it’s a day where there is ice around the hangar entry and a snow shovel won’t remove it all, then you either take a little “run and go” to get sufficient momentum to get the aircraft into the hangar, or you use some powered help.
Personally I’m familiar with several hangars where it will not be reasonable to try to run the SR20/22 in, most people simply can not control the tow bar, with 4 or 5 inch lateral precision, with one hand, while pushing the a/c “uphill” at a slight run.
How much clearance will you have?
I’ve never had the opportunity to use a

have never really seen a need or a desire to
The SR20/22 are fairly light planes. Pardon
my ignorance, but “why bother?”

just don’t know.)
