My first mod...Diamondback SE

I just ordered a Diamondback SE tonneau cover. I also ordered the 8 inch bin and 4 extra tie down cleats.
I don’t officially have my truck yet because of the recall...but when I do get it, the tonneau will be the first thing on it.

 

I love mine! I am still plugging gaps and running after small leaks in the front bulkhead. Not really the cover leaking but the bulkheads and gaps up in the front of the bed. I don't have the bins or extra cleats but love the security of it.

 

On both sides of the front rail there is a gap, just fill that in. I used silicon and I've had no leaks from the front of the bed. When I adjusted the locking devices I ended up having my daughter sit on the corner I was adjusting so the cover would be pulled done enough to have the rubber seal work well.

 

Yes definitely some weight on the corner you are adjusting. I added Butyl rope to the corner gaps this last weekend and pretty much stopped my leaks.
I put a little bit of black acrylic paint over the top of the butyl tape and it doesn't stick to the gasket.

 

That looks tuff!
