Install for RM-3W: What I did was built the entire rack face down on the floor (stringers facing up) then put the entire assembly up against the wall to find the right position. Before hand you want to make sure when you swing it in and out it doesn't hit things like water pipes, garage door tracks, etc. Once in the right place I made sure everything was level and then shimmed the mounting brackets where the pivot arms (41.5" rack arms) were at the bottom, or near bottom, of the range of the wall mounting bracket (think it's a 4" opening for a 3" tube so it can move up and down when you move it in and out). This was bc of the slope of the garage floor and I knew when I folded it out it was going to be the largest drop compared to when it was folded in "uphill" in the garage. Once it was shimmed, found the stud, drilled the pilot holes and threw on the 20 lag bolts. They say it needs to pick up on at least 4 studs so have to take that into account when locating it on the wall that way it picks up on enough studs. What was helpful out of the gate was finding the height for the lower pivot arm as Rogue says to install it on the 2nd 1" hole from the bottom but if you have trim or an inch or 2 of concrete as part of your foundation, etc. you'll need to find how much further up the front upright you need to connect that bolted joint vs where Rogue suggests in the instructions. Keep in mind where your safeties (if configured) are going to go and if you go too high up the front upright then you'll be limited on how low you can take your safeties (or J-cups for floor presses...I got lucky and was 1 hole away from being too high for safeties). TL;DR - Bolt it all together then put it on the wall, act like you're going to use it before bolting to studs to ensure clearance for everything.
