I have a 99 Hawk that is not thermal pack ready. I can handle installing the lower velcro on the wall, but am having trouble coming up with best way to hang it from the ceiling. I thought about using flat head self tapers to attach the velcro on the roof perimeter tubing. But I am concerned that at some point the screw heads will wear through the vinyl siding while it is in the down position.

Any ideas?

Contact FWC. If you are purchasing the thermal pack from FWC I believe it comes with the Velcro. At the very least they can share what you need and how to install it.

I am not buying it from them. And to install it like they do, I would have to completly remove the the vinyl from the roof. Then sandwich the velcro flap between the roof frame and the vinyl. Thats how I will do it if I ever have to replace the vinyl but at this point my roof and vinyl are in great shape and am not interested in pulling all those screws out and hoping they will pull tight again.

I believe the Velcro on our 2014;Grandby was adhered to the top of the vinyl (self adhering) and the bottom Velcro was self adhered to the top of the hard side. Why would you have to remove the top of the vinyl at the roof?

Build your own. A roll or two of Reflextix and some velcro and you could be out less than $200.  The FWC one retails for close to $800.

Yours must be different than the 6 other FWCs I have been in. All the ones I have seen have the upper velcro sewn to a 4” section of vinyl that is then sandwiched between the roof and the the vinyl sides. Here is a pic. You can see the perforated head liner and then the white vinyl with velcro sewn on.

I have done the reflextix. Tried both inside and outside(condensation testing) and i am moving away from it cause the noise when its windy bothers me. I think that crinkling noise just cuts through my sleeping brain and wakes me up.

But I have sewn up a a thermal pack using a quilted jacket liner material and am just brain storming the upper velcto mount at this point.

Hard to tell from this pic, but the upper velcro mount hangs from the same mounting location as the vinyl . You can push it up against the vinyl or push it up against the roof.

Hey Sloth,

 

If you could purchase some polyester reinforced vinyl (usually comes in 60” width, and sold by the yard), and cut into two inch strips, you could put them together end to end to get your camper length, then have the 2 inch Velcro stitched on top. After that, you could use HH-66 vinyl cement to attach to the top of your side liner, providing a very strong contact for the top attachment of your thermal pack, and as you have suggested, using self adhesive Velcro to the camper wall on the bottom. I’m not sure using self adhesive Velcro on top would provide a strong enough bond to hold the weight.

 

I’ve attached a couple pages from my build thread to provide info on the vinyl cement, and how I made my thermal pack Velcro strips incorporated during the installation of the side liner.

 

Just a thought of one method that might work.

Perfect! Thanks thats exactly what I was looking for. Thanks so much, i am going to order a can right now. Did you lightly sand the the sideliner to get a better bond?
