Got a little more done, gravity water fill #1, idea was sound, didn't quite put the fill hose at a nice enough angle so rebuilt it.
Version 2.0
Got the awning, was nice just to drill and tap all the mounting holes. Using a Dometic 9500 case awning, no arms, fast deploy and retract, auto rain dump, I like it.
Got the rear storage locker finished and installed, this will hold all 4 jacks plus other gear, or just a lot of other gear, rails extend from horizontal extrusions for more options, bike rack, stuff like that.
And had to pick up a small crane in a hurry today, 3662 pounds! No problem, rear springs were feeling it but that's soon to be a thing of the past.
