Well, here's what I did. Per Hopkins I attached the repeater to my bed cover at the very back of the truck and can plug it in to the 12 volt plug I installed there. I couldn't find a box that was appropriate for the size of the repeater with the antenna's extended. We have a trip planned in two weeks so we'll see how this works. If not I'll punt and try something else. Thanks for the suggestions.
