Is this mod possible for a RetraxONE?

Hi-

I'm going to be looking at a used RetraxONE tonneau cover (believe it's a MX, non-railed version) and have a couple of questions I could not find answers to, so thought I'd try to get responses from other Retrax users.

1. Since I'm not familiar with the product and wear patterns of this cover, are there anything, aside from the parts list that I need to check? Parts that wear that might make this a deal breaker?

2. The model I will be looking does not have the rails. Is this something that can be added to the existing rail Retrax rail system? Are the rails between the MX and RX models interchangeable?

3. I'm assuming the model is MX, was there any versions prior to the current lineup that might no longer be sold, which might create compatibility issues, if I try to swap rails?

Thanks!

 

I contacted them directly you can swap the mx rails for the slotted xr rails its 400 bucks though
