New and Nervous

from what i remember, the Thermarest tent ends material was not the vinylized canvas, like other hybrid tent ends.

it was more like actual tent material, like thick nylon.

here's a pic:

X2 on using your local marine canvas repair shops. They do incredibly great work on canvas repair and much less expensive that using a Quote and Unquote "RV" highway robbery shop. :C

Another good reason to search this Forum for the make/model of rig one is contemplating purchasing.

Hate to say this but from what I remember of the Thermarest tent ends, they mounted differently and were supported differently than conventional tent ends.

There may be more than just new canvas.
I would first contact Bear Creek, since they've been around for years.

They also might might take your old one and fix it or make one with the old one as a pattern.
Unless they already have made replacement ones.

The Thermarest tent end was unique and had some positive features.
But issues with water drainage and their infamous futon-style mattresses doomed the Thermarest and left the Kodiak/Cub hybrids with bad rep.
That brand hasn't been the same since.

I've heard good things about Sunbrella material, FWIW.

Look up canvas shop in your area. They can you the old one as a pattern to make a new one. Enjoy

Welcome to the forum. As previously suggested try Bear Creek Canvas or a marine upolstrey shop.

I had some tent material problems here with my regular three room ground tent and was able to get it all resolved with a local boat fabric repair place...

I'm pretty sure if you can take it to them then can repair such things...
