Thanks everyone for their input, after searching around and reading reviews I ended up ordering an Arcan 3 1/2 ton jack from Northern Tool. It has a nice low profile and good max lift height at 21 3/8".

Not the lightest jack out there, but should also allow me to work safely on the SUV.
Thanks again!
