Stan is correct. You don't want to push the camper around on its jacks. They are like large levers hanging off the side of the camper and will certainly do damage. I built a simple dolly for my Hawk from ideas I got from another post on this forum and it works great. The platform has pretty much the exact dimensions of the base of the camper. I built it just like you’d construct a 2X6 wall, with 2X6 “studs” running the length of the camper on roughly 16” centers. Think of them as floor joists. I used a sheet of ½” OSB as the base which provides the shear, and I put a couple of partial pieces on the underside for added measure (probably not required). Think of this as a subfloor. I then used a 2X8 at both ends that measures a bit wider than the camper base, but is still narrow enough to slide between the camper jacks, to attach the casters to. This provides a slightly wider “wheel base” which makes the dolly extremely stable. I have high enough garage doors that I can drive into the garage with my camper on and remove it. Then I slide the dolly underneath the camper, lower it down, and I am set to move it anywhere I want in my garage. This is definitely the way to go. I agree that you should go with the largest casters you can get. It makes rolling a lot easier. I've attached pics of the dolly posted by the gentleman I got my ideas from (the one with the camper loaded) and a picture of the dolly I constructed (the one with my truck's tail gate on it). Good luck and congrats on the new camper.
