Thanks for the tutorial! Got mine installed today but it took me far longer as I ran into a few problems. Of course as far as projects go I had to make that obligatory trip to the hardware.
Where I ran into problems were yes, those bolts are on tight and I don't have an impact wrench. I put some WD40 on them and got all but the last one! I ended up fashioning a redneck breaker bar by cutting a piece of pipe and sliding it over the 1/2 in drive. It didn't take much to break it loose with the extra leverage.
Next problem was that there was a big ole weld burger right where the axle riser was to be installed and it was enough to cause a noticeable gap on that end. I got my angle grinder out and carefully ground down the burger without getting into the rail. Channel now fit snugly on both ends.
All righty, time to bolt everything into place and tighten to 120ft/lb. Getting close now......not. The lower bolts were easy enough, even though its slow going, but the ones on the frame bracket were a kitty "b" as I had to use an extension on the drive and it kept slipping off of the bolt head. That's where the hardware trip came in. Went and got a deep well 15/16in socket and that was just the ticket. All done with that, put the tires back on, tightened to 100 ft/lb and then raised the E2 receiver up, significantly too, with the rear end riding just slightly higher than the front.
I'm a happy camper and no longer worried about scraping my pins that hold the stabilizer bars on the E2 hitch any longer. This is how the camper should come from the factory!
