I've left mine plugged in because I've been in and out a bit while doing mods. organizing the inside and such. Its nice to be able to pop up, have lights and turn the AC on when I am working.
I keep thinking about putting a battery switch on, but have been waiting to see if the dealer setup will provide enough battery power for a long weekend before making power mods. So far so good.
