Would recommend providing you don't get a lot of wind where your RV sits while covered...
I have the 2011 3010 which physical length is at 36' 8"... I picked up the 37' Designer Series 3 layer RV cover from ADCO #32856. It fits just right... make sure you prep your RV by washing it/ turning down or removing your antenna and using something like pipe insulator w/tape to cover the gutters or they will work their way thru the cover with-in the winter season. Snug up the cover so it doesn't move around while placed over the RV. Used mine thru one season so far on the 3010 and it worked great! Enjoy your new Cyclone!!!
