At Yellowstone last summer, I saw plenty of canvas tent rentals. They're heavier and cost more, but some campers prefer them for durability. Nylon is just more common now because it's lighter and cheaper.

Got an old laptop I only use for booking trips, works like a bootleg VPN.

You mentioned it's not a science project, but the mix really does matter. If the filler separates, it won't work right and can make a huge mess. That means you waste money and time cleaning up. Doing it yourself ensures a consistent mix that lasts longer. Sure, it takes a few extra minutes, but you save hassle in the long run. Have you tried both ways and seen a difference?
