Ended up cramming all our luggage inside the tahoe. It doesnt appeal to my husband. Comfortable, sturdy and amphibious! ?? They are too wide but i put in little foot cushion thingys and now they fit well. I mapped out a 3. I installed it a few weeks ago and used it several times. Overall, this works, but the packaging and directions suck. 37 in Pumps usw. Was missing several key parts; not usable. Would highly recommend and buying some for Christmas presents.
