WALMART - LOWES - AMAZON is where I get 99% of my needed supplies...
Back in 2008 on Day 1 of my off-road popup trailer my big cat jumps on the roof when I opened it up and put a whole bunch of little holes in the roof...
I don't think I would have ever got any leaks from them since they were so small but it was two days old yet haha...
I ended up putting 9X12 tarps over my bed ends anyway. make it cooler in the summer and warmer in the winter and cuts down on the bright sunlight on the insides..
These are my poor man GIZMOs I guess...

My tent bed fabric looks like brand new even after all these years...
