I have read through many of the thousands of previous posts on tonneau covers. I don’t want to rehash ground that has already been covered. My question is this: Those of you who bought the North Mountain roll up cover have now had the, for several months. Are you still happy with your purchase? The comments I’ve read are generally days after install and very positive (except for the instructions). But I’ve seen a few negative posts start to pop up. Thanks in advance for your updates.

Love your truck, I just bought the same one on Saturday 1/15/22 after 14.4 years in a 2007 RTS. I found a 1-year old WeatherTech rollup tonneau on Facebook Marketplace for $200 (asking) but am looking closely at the North Mountain on Amazon. How was the install on your cover? Thanks
BTW, loke what you did with the clamps.

It was very easy and straight forward install.
OK need some help from the NM people. Two issues. First, water does pond up a bit on the cover. To me it seems obvious that there are no bows in the cross bars. Has anyone tried bending the crossbars to create a bow?
Second, the tonneau does leak which is expected. I sealed the bed corners/channel with silicone. It all seems to be coming down the back wall of the bed. The rail by the cab does not seem to be sealing well. Any ideas on how to make this seal better?
Thanks,

Ok not sure if this fixed it (no rain), but this seemed like an obvious solution.
The position of the gasket does not allow it to seal on the bed very well. I just heated up the gasket, and moved it to a position that would allow better sealing on the bed.

Not sure that you can seal at cab end, the soft pipe insulate form that attached at the cab end 3/4 to 1 inch thick,unless you replace with something more solid plus the tonneau bellowing while driving the air must escape somewhere. the water enter the bed are not that much and ran between the bed rail I have travel with luggages on truck bed after placing them on a thin piece of plywood and no issues with water .
So it still leaks, coming from under the gasket going down the back wall. However if I compress the gasket, by placing a 12 lb weight on the top of the tonneau, then the gasket does not leak a drop.
Clearly it’s an issue with the design as the mounting brackets are not able to compress the front rail down with enough force. Not sure if there is a good solution.

I attached an elastic strap from the center of the tonneau rail down to the bottom of the bed ... that provided more tension on the rail & compressed the gasket.
Does the strap work?

Not perfect, but better than without it.
I’ll give it a try, tape doesn’t work specifically under the hot sun they curled up.

Had mine on for about 6k miles now. Handled heavy upstate NY winter very well, no issue at all despite heavy snow. Flaps a little at speed but then again every soft cover I've owned did. Much less movement after I adjusted the tension as per instructions. I do not expect a soft cover on a Honda Ridgeline to be watertight nor do I care. Overall not as well made as my prior cover but close, and at 1/4 of the cost, a win overall. Would buy again, great value.
I agree, as well as expected for softcover and for what it cost. It hold up well on the hwy with 60 mph crosswind and my main reason is I can setup the Ridgeline tent without remove the tonneau

Installed mine last week in about an hour, nice piece and provides completel bed access. Haven't had it leak in the rain yet but haven't been a monsoon either - just drizzle. It does flap a bit and there are some stray thread strands popping up from the stitching (that may be normal) but all-in-all pertty unbeatable at the price point.
Ok so I may have found a fix for compressing the gasket on the rail by the cab. The issue I noticed, is when I moved the gasket forward, that cause the front rail to twist up by the gasket. You can see in this pic the rear of the cab rail is being twisted down to the bed.

Using some basic hardware, I bolted in two pieces of support metal that prevent the back of the rail from twisting down. This allows the rail to put more pressure on the gasket that has been moved to the front.

Its tough to get a good shot of the gasket being compressed, but it definitely is. It already passed the hose test, which it failed before. Need to drive it for a while, will let you know.

Received and installed my NM tonneau yesterday.
Didn't go through any rains yet, but I'm expecting a leak from under the "cab end" gasket, cuz even if the front rail pushed all the way forward and outer pleather cover literally pressed against the C-pillar panels that hard that I can't insert a piece of thin cardboard between the cover and pillar panels, about 1/4 of the gasket width is still hanging in the air not squeezer between the front rail and plastic bad cover. The gasket is installed all the way forward on the rail, there is no room to move it any more forward.
The portion of the gasket between the front rail and bed cover is squeezed pretty well and I haven't noticed any rail twisting yet.
I'm afraid if a cover is pushed all the way forward the cover's vinyl would rub hard against the pillar panels and wear out the paint.
Also, if the cover is pushed al the way forward, the tailgate is barely covered by the cover.
I've mounter the cover in the position where the front seam/ bulge of the cover is barely touching the C-pillar panels and covers the tailgate pretty well, but about 1/2 of the gasket width is not used.
Q: the kit came with a strip of self adhesive weather foam. Neither instructions or installation video mentioned this strip. What's it for?
And has anyone tried to insert a sheet of hard cardboard or some plastic sheet between the cover and 3 middle rails to reduce "flapping"?
Overall I like the cover, the vinyl looks pretty though and seams are straight and neat, I just wish the front rail was a bit wider with better rail to bed cover seal.

I don’t remember the adhesive strips. I don’t think it will hold and keep it from flapping. Last year we took a 7300 miles road trip , we were worried the tonneau fly away on HWY speed and with 50-60 mph cross wind at southern colorado but it hold up.
I stacked some weather strip foam between the cross rails and the tonneau. I stacked them up about 1-2” height, 12” long of foam at the rail center point. This creates tension between the rail and the tonneau. Plus it creates a high point in the middle of the cover to help direct water. It reduced flapping of the tonneau as well.
A nice design upgrade would be to bow the cross rails so the center was about 2” higher than the perimeter.

You have to make sure that front seal is tucked up and over the bed front rail...I ran my fingers down there and stuffed the seal up tight and no leaks so far you also need to seal those valleys that are clear all the way into the bed behind the cab on the rails...use strip caulk or closed cell foam.

You can push a Popsicle stick through them all the way into the bed.
