I also have a HF platform lift. Best $300 I ever spent. Replaced the front wheel chock with the HF upgrade (http://tinyurl.com/HF-chock-link) and have been very pleased.
My Venture has been on it for the last month as I went through it rear to front. Purchased a small jack from HF to lift the belly so I could get the rear wheel/end off using the removable deck opening. The KLR is now up there for some engine work.
The Venture is a little heavy for the HF unit to work smoothly. Kind of jumpy when lowering. However, steady as a rock when being held in place.
I drilled several additional tie down locations along the side rails and installed loops to hook to.
And I agree with what was said earlier - if the 3/4 steel holding bar bends, there is something really wrong going on.
I understand there was a batch of these lifts sold with a flat top (edges were not bent up). These allowed the top to bend and fail. Make sure the unit you have has the right angle bends on the sides (about a 1" lip on each side).
I would buy again. Although, if a used Handy lift falls into my hands, the HF unit will be for sale immediately.
