I'm thinking about getting one of these to help maneuver the boat into a tight location. http://www.powermoverinc.net/
Questions for people who have used them:
Has anyone tried lifting one in and out of the back your truck when you go to your storage lot? They look like they're pretty heavy.
Has anyone tried to plug the AC model into their car cigarrette lighter plug using one of those power inverters that turns DC into AC? Would that draw too much juice and break the inverter or something?
