May have to go with something like this and get all the tall adapters I can to safely go higher. I have the complete building blue prints for the whole facility and I take this footnote to mean that the 3000 psi rating is for the concrete floor of where I live and the outside concrete rating of 2500 psi is in my carport area and therefore would not support the Max Jax. Hence the questions about the creepers and this portable lift set up.
