My bed rail caps are still on with the canopy. The cab side width of the bed, they just stacked 2 of the rubber weather sealants on top of each other and that fills the gap fine. I get dust in the bed from other places, but never any dust/debris/water through that side.

I could be wrong but I’ve heard the bed rail caps don’t come off very pretty. If you can I’d try to keep them on👍🏼

 

Exact same thing for mine - rails on, double up weather proofing tape at the front. Been this way for 14 years now.

 

If you take off the rail caps won't the tailgate cap cause interference issues.

 

I left mine on, actually, I added some before putting my topper on. If you don’t then the bare tops of the bed will actually be lower than the tailgate cap and - in my case anyway - the drop in bed liner plastic that wraps up and over the front of the bed.

 

I’ve got a soft topper on one & a tonneau on the other & didn’t even try to take the bed caps off.

 

The tailgate cap gets replaced by a different style

I'd leave them alone. They protect your bed tops and are glued in place, and as noted, a few sections of foam under the topper and Bob's your Uncle. I don't have one now and may never have, but if I do, this is exactly what I'll do.

 

Thanks for the input. I'll leave them on. Yes the tailgate cap has to come off for the model I'm getting. There are models where the back hatch is made to accommodate the cap.
