I have a 6X12 enclosed trailer with E-track I ordered installed when I ordered the trailer and I have a ramp door. I have them wrapped and strap them down securely ...I take my pins to shows in it all the time, and no issues. If you rent that particular trailer, you also have to worry about weather issues that you don't have to worry about with an enclosed trailer... I would not suggest transporting pins with legs on ever (but that is just me) I also generally do a check of connectors and such when I arrive and unload/set up the pins at the show to insure that anything that might have worked its way loose gets re seated to not cause any issues. These are electronic devices and things do happen, but with a certain amount of caution and "common sense" (not sure that is the correct phrase but if you wrap it strap it and check things out) when you set it back up then you should be good to go!

I can fit 8 in my 6X12...I have a side door on mine, so fitting 8 is a bit tight with 1 overlapping the side door a bit.

Nope it is a single (Dexter) axle. Looked at the double axles, but did some research and decided that for the extra expense and what I wanted it for, the single Dexter axle was just as good ride wise (IMO). I haven't had any issues with it and I've had it since 2009.
