Onex Canopy Issues...........
If you send me your email a.d. I can send you photos of the canopy installation (I have a LOT of photos of this). I think Bryan Cotton's is a Sonex which is much different than the Onex although he may have some good tips as well.
I have done 4 RV tip up canopies over the years and this Onex was a bigger challenge than any RV canopy. Mine resembled a "Plexiglas football"........the sides stuck out 3" from the frame......however I did NOT heat the canopy for fear of permanent distortion......once I figured out the method, I was able to draw the sides in and drill it to the frame.
The finished canopy turned out really well but it was not easy.......go slow and don't get in a hurry......and use "plastic drills".
