This thing is awesome. I use it to haul my 16 foot Navarro Loon canoe during the warmer months. I've hauled the canoe over a mile on some rocky terrain using this cart! Its very smooth rolling and easy to use. I like that it folds up.
In the colder months, I use it for an "unintended" use. I use it to haul my duck hunting gear! My duck hunting gear is in a 5' long plastic jet sled, which I strap down onto the Suspenz carrier and push for 1-2 miles along dirt paths and levee roads until I find a spot I want to enter the marsh. I then slide the sled off of the cart and float it through the marsh. Because the Suspenz cart folds up, I can easily fit it on top of my sled once I'm in the water. Then when I'm done, it all folds up nicely and fits easily into my Subaru Crosstrek.
This wouldn't be possible without the adjustable bunker bars. Overall, a great product that I use at least a few times each month.
