transporting a dish tailgater

I was thinking of theft when I mentioned about a pole mount coming off the ladder. but other wise I feel a roof mount would be my best with the removable mount that king has offer. but my problem is if we are in tree cover, then the dish would have to be moved for a clear signal. and that is why I was wanting info on a ladder mount that could be used to raise and lower so I would not have to climb the ladder. or some of the ladder mounts that are out on the market that is clamp on which I have seen that you do not want to transport with the dish mounted or am I wrong on the transport with the dish mounted fast to the ladder mount? (hate to have to drill holes in the roof)
