I got the Jack Kit from Equalizer two weeks ago and contacted a local welding shop. The owner said to prep the brackets by grinding the paint off the edges where the weld would be and grinding a bevel along that edge as well. In addition, he said to grind the paint off the frame area where the jacks where to be installed and clamp the brackets in place. The welder suggested going down to Harbor Freight and to buy a hand grinder if I didn't already have one. He said I could buy one there for $12.00. I thought that sounded way too cheap but to my surprise, I found one with a grinding wheel for under $20.00! It lasted long enough to finish the job (and is actually still working). I also bought the C Clamps at Harbor Freight. Doing this prep work saved me a ton of money at the welding shop. All the welder had to do was lay 8 vertical beads on the brackets and they were done. Total welding cost was $300.00. I had a friend that said he could do it for free but it would have cost $135.00 in gas and delayed the project by two weeks. Me, being the impatient type, went for the quicker, more costly solution.
Next (after driving the MH home), I bolted the jacks to the brackets, ran the hydraulic lines, mounted the leveling "Brain" under the floor, ran the electrical harnesses, wired the pump to the battery and mounted the control panel near the driver seat (actually it is still laying on the floor beside the driver seat). I found a large rubber grommet near the steering column that was easy to pull down from below and modify to run my new wiring harness up to the driver's control panel. It isn't rocket science, just a lot of labor.
The Equalizer jacks are quality constructed and work great. My only beef was that the instructions could use a little editing to make them clearer.
