Purchased a Four Winds 5000 23rk this September. We also have a 24 foot TT. The TT lost its spot in the garage to the MH. We have lots of snow and wind here in Idaho. I've covered a previous a MH, before the garage, using a big blue tarp and lots of rope.
I used a big blue tarp from Harbor Freight. This time I bought three yellow tow straps 25 feet long with loops on each end. Put the tarp on, the straps over both ends and one in the middle. Tied the loop ends together under the TT, than ran a rope all the way around trough the loop ends that hung about two-feet from the bottom edge of TT. I ran a small rope through the holes at the bottom of the tarp crossing under the TT. We had 50 mph winds already this year. It flaped a little but never moved. Before, when I just used rope over the top, it would loosen up and flap like crazy.
