Check your tire pressures and make sure that the skylight is completely
down.If you wait about 30 min after getting home , your pressures may be
about 5  psi less.Fill up w/gas and maybe adjust your pop top to close a
fraction tighter. The handle where you squeeze has 2 bolts w/adj slots. It
may be harder to squeeze when you are done adjusting, but all that work, it
may be worth it.Also maybe a shim of somekind in the roller track on your
garage door. You only need a tincie bit of space.Maybe several of these
ideas and a couple of others will do the trick.
