UJoint looks impressive and it's GOOD news to me that Quigley will do a used unit ( They did mine in 2004 and it was used with 20k miles and after they did it said they would NOT do another used unit )......so, glad that's an option. They do first-class work and changed the axle gears in rear to match the new Dana 60 front end. Raised the body about 2" and did first-class welding everywhere. The manual transfer case has been flawless as well and really like the high/low range for getting out of the really soft sand. I put taller tires to also increase ground clearance. If I ever had to do this again, Quigley would be my choice. Hope you can get the RV of your dreams as I certainly did.....years and years of fishing late nights under a full moon and when everyone else is packing up to get lunch/dinner, I just smile and fire up the grill or oven and never leave the beach!
