the problem with IdleAir was the charge per hour. I know it's cheaper now, but I don't remember how much. Most of the shore power Ive seen advertised seemed to be priced really high too.
A nice, nationwide network of reasonably priced shore power is what we all need, but that's quite an undertaking.
I know I saw some shore power modules at a truckstop northeast of Charlotte on I-85. I don't remember what exit. Until there is a nationwide network though, we still have to be able to heat and cool our trucks without it, thus eliminating the need for it.
