I have a vinyl sail tracked bed base attachment strip on my tent section [ reusing my old side fold tent section ] the vinyl should be able to take many many years of being clipped to the new campers bed base in this way [ only down side is carrying the 6 bits of clip in poly tube sections ] .. If it did ever a wear hole in one spot, a small bit of vinyl repair tape either side of it would fix it easy enough.. be cheaper than having to replace two worn out Velcro strips ..
Cant fit it permanantly as the bed bases slide in / out ..
Im thinking for us, this is a more positive way of fitting and a lot easier / cheaper than having to have a trimmer alter my tent sections .
Still a bit more thinking to do on it yet though .
