Drilling holes in trailer roof to install solar: worth it?

One consideration - portable solar panels can 'disappear' sometimes if you're not around..... not to mention the hassle of setting up or putting away everytime you come and go. 3M VHS tape is proven to be a good way to mount solar panels on roof. However, if you're not physically or skillfully up to it then maybe you should either use portable panels or drive over to Springfield Oregon and visit AM Solar.
