I have a 35' Newmar Class A and am shopping for the BEST tire covers, I've owned the vinyl type that attach with velcro in the back but found them to be a pain to connect the Velcro especially in acclimate weather or surface conditions, ie; mud, dirt or rain. Looking at the Snap Ring type and have only found one company so far that had a nice product which is Covercraft with lot's of good reviews. Problem being they are 4 weeks before manufacture plus shipping time of at least another week. They advised me to go to Amazon but have found the size I need (Extra-Large 36"-39") are out of stock. Covercraft told me they're having a hard time getting materials. Anyone know of any other viable options or even reviews on these, maybe I just need to wait. Thank you!
