Regaurds to info on axle flip: It was very easy with simple with basic tools, torque wrench and a welder. The $24 went to axle saddles bought from a loacal trailer shop. Now I thought you had to repace all Ubolts, do to stretching, but trailer shop said if they were in good shape use the old ones. The hardest part was jacking up high enough to get axle off the ground and putting in, good, jack stands. The most cridical part is getting those axle saddles located but with the old ones already there I located just opposite those, not so hard(messure, messure, tac, messure, finish weld, messure, clean and paint) This is nothing like locating saddles on a new axle which can make messuring x12. There are things like dropping one side of leaf and cutting brake electical on the one side. It only took me about 5 hours by myself well I do have a 8yr daughter who wants to help with every thing. Could have done it in 4hr but nothing like having help, I love it.
This all said, do not attempt this if your not sure of your skills or equipment/tools. Putting that camper up on stands and being under it is nerve racking, even though I did one axle at a time. Do not attempt to weld if your not up to it, this is a critical weld and needs good, good penetration.
Have fun, Good luck
Keep the shiny side up
