Automatic satellite systems

Heres one for the familys who still like to watch TV when away.I was given a trypod and satallite for free ive used it a few times and its great having my sky HD from home but with the cables,trypod,setting up and kids,dogs !! i was thinking of upgrading to a roof monuted system for my van.

does anyone recomend a model and how easy is it to fit,does it require holes in the van for fitment or just put on the roof when on site?

thanks
