FULL-STANDARD MR66

Definitely needed two. I can see from the videos where one could handle installation, but it just vastly better to have two. If you have a compressor purchase the compressor adapter. If you don't have a compressor then consider purchasing one. Pumping up the sides wasn't that big a deal. However, pumping the top was a chore. Mechanical air...the way to go. Looks good on the truck. I haven't been in any weather yet so I can't speak to its water integrity. We'll see. I hope it is worth the investment.

Install was easy, videos were helpful. Drove from Milwaukee to St Paul and back last weekend. Topper moved back on bed about 2 inches on drive up. Retightened straps, no movement on drive back. Will purchase new rear door soon. Hoping to camp in it this fall. Great product!

My grandson ~6'3", 220# was afraid he would break it when I told him to stand on it. I told him that they drove a wheeler up on it so he couldn't hurt it. He, his mom & cousin were impressed as is everyone I show the pictures to. It is a tad long for my 2015 F-250SD, so the topper rubs the rear of my cab. The front panel also cuts off the top half of the cab's rear window. No biggie if you have a backup camera or are proficient using just your side mirrors. It has held up so far with no worries about coming loose during a high-speed highway run or letting water in during a few torrential downpours we've had. I got the first gen of the replacement inflated rear window as well. Some issues I'll address in that review. Oh, and by the way, it is heavy. Maybe the short bed versions aren't, but it was all I could do to get it up on the truck. It would be best to phone-a-friend.
