So, I'm going to swap my side opening Smittybilt RTT to a rear opener and I'm looking at the instructions and it says I will need to cut the mounting rails on each side...but I'm looing at it and I'm wondering why. It seems like keeping those extruding out would both give some good handholds for lifting it onto the roof and also help secure/stabilize the folded out section. Anyone have an opinion on that? I'm talking to a VERY small group of people I know. It's a bit of a headscratcher for me though.
