I am pretty certain Relik is a TROA dealer, like (full disclosure) me.
Regarding lead times: TROA makes a top in the order they are received. Bows too. They serve the world, not just the states. It’s getting ready to be soft top season and folks are placing orders at a higher rate. I know inquiries always spike this time of year for me.
I’m have, on occasion, been able to jump in line for a customer.
Customs can also delay your top, just a fact and a crap shoot.
Regarding the straps failing from leaving the vehicle outside: it should be a part of regular maintenance to apply a UV protective to your straps quarterly.
Look into 303 protective spray or other products from the the RV industry.
