The DW and I use cell phones (we've since found our old walkie talkies in case of no cell signal). We both scout out where we want the trailer and check for obstacles for our slides. The DW directs me in with few problems. The one thing I like to do, since we have the wide spaced axles, is once i'm in the area we're happy with I pull foward and make sure the TT/TV are straight and back in again, I believe it'll take the stress off the axles. I guess it really depends upon the site you're at
I also wont move unless I have a visual of the DW in my mirrors
