I park my Dodge 3/4 ton quad cab with long bed in this 12 x 28 with room for riding lawn mower. This is a very solid unit if you get it anchored well. To anchor the building, I dug 8 post holes 32 inches deep, filled them with concrete and into the wet concrete I inserted the provided augur anchors. It takes about 100 lbs of concrete per hole. Negatives: The provided steel cable is too light for connecting building to anchors. I purchased heavier cable and clamps. The instruction manual has errors. Phone support was pretty good though. The posted installation time is probably a world record time. It took me 4 hours to just inventory everything. This was also due to errors in manual. You should plan on it taking about 3 plus days if doing it by yourself. This would include digging post holes and setting anchors in concrete. Installing the legs and tarp will require a helper. Two of us did it, but a third person would be easier. I purchased additional locking washers to use on all the bolts. Postives: The building is very stable in strong winds. A well designed unit.
