What is it about the Retrax that made you feel like it was worth $500 more than a Revolver X4S (or did you mean BakFlip MX4?)?
I was indeed talking about the X4S, as I just removed the Bakflip MX4 cover from my truck. It didn't work well with the MX4 cover, only 2 panels opened and the 2nd one would have to rest on the Rambar.
Why did I think the extra $500 was worth it. The Retrax just over all feels more premium even with the Polycarbonate (Lexan) material. I also liked the XR rails (extra $129) so in the future I can built a racking system for stuff like bikes, kayaks, cargo basket/plastic box etc..
I def would have gone with the aluminum, but I just couldn't justify like $1400 more for it over the cost of the X4S. The PRO would have been over $3000 in Canada and I don't use my bed daily. I still think the ONE is a great cover and it won't get as hot in the summer compared to the PRO. Time will tell.
Most of all, I just liked the way the cover works. Yes I loose bed space but it's easier to open and close with my truck being lifted. I think the X4S would be a little more difficult rolling up and strapping down with the lift and the Rambar - I'd have to get up into the bed to lock it down. Plus I like that I can open and lock this anywhere along the bed, where X4S is open all the way or closed.
I see you mounted it over your Rambar. I have the same setup (RetraxPro, but it's an XR) over a Rambar. If you're interested in getting the forward section to sit a little more flush, here's what I did:
Bought the flattest-headed bolts I could find that work (don't need the female half, just the male bolts):
Before and after pictures. Still not "flush", but it closes up the gap better:
I'm good with what I got, the bolts and gap are perfect plus I don't want to take it apart again to change the bolts haha.
I did think about those connector bolts, my concern was they are something that is used for furniture so I was worried about strength. Plus they are not stainless so they will eventually rust.
I may think about it down the road but I think with the added foam and button head bolts I'm good. But I appreciate the suggestion, I may do it down the road. I'm always changing things.
