I have that exact lift. Not a single problem with almost a years use. I use it all the time on my jeeps. I also have the professional series 2.5 ton jack for about 3 years now and no issues. I know there are bad reviews but I have never had a problem.
I know first post, been lurking for a while.
Have you thought about expansion in the future in the electrical area. As in, 220V outlets for possibly a welder etc??
So far it looks great man. Planning something similar myself but have welding and fabrication in mind. Just a thought. :beer:
