…I’m still getting the curtains blowing out at the front partially blocking a bit of my mirror
Sounds like the curtain is old and stretched. Get this all the time with ours on the older trailers - total pain. Good luck getting anyone to fix it, ie not much of a hope.
If its got a ratchet on the curtain at the back then tension most on that but a lot don’t. Assuming the ratchet works.
If theres a hole in the curtain at the top it will do this (might get that fixed as it can rip).
Eventually you’ll get a better truck with better curtains, but initially it’ll be the crap. Btw, if the curtain actually slides without putting your shoulder out, thats a bonus.
