I'm tired, our garage door hardware is broken & we can't seem to fix it
, and we're supposed to go camping tomorrow, so welcome to the board & I'll make it brief (I'm usually more friendly but..)...instead of trying to glue the velcro back onto the walls, you might want to order some of the new round velcro patches from the factory. Tommy from Custom RV gave us some at the Petaluma, CA rally, I haven't had the chance to try them out yet. Ask the factory how to attach them and for the hardware to install them.
Have fun with your TM!
