+1 on the Quick N Easy brand.   I have a bike rack from Yakaima that is
mounted on my rear hatch for my bikes but I also sometimes need to carry
heavy long lumber, ladders, re-bar, sailboards, etc.   I have a set of
Quiick N Easy towers with yellow cedar, painted.... 2x4 cross bars, some
galvanized eye lag bolts screwed into the edges to make tying stuff on
easier.   Quick N Easy really are quick and easy to mount up on the roof.
With some gutter adapters, they'd go on a pop top, too....They attach with
a cam-lever that is much quicker than Yakima or Thule. A quick snap, and
they're on with the proper tension, etc.... The Quick n Easy is meant to
use with a galvanized water pipe cross bar but I adapted mine for stronger
and easier on the load wooden cross bars.

   I know the OP was about racks for a pop top, but later it was mentioned
about bike carrying.  Here's a link to my solutions for that..and other
stuff I've done on my low roof camper...
