I love the build! You keep squeezing every inch of storage out of it. I have been meaning to make a removable female hitch for mine. Perfect spot for the grill! I put a few receiver hitches around the sides for my grill and maybe a "U" shaped toilet to keep it close to camp. I haven't read much of your comments, just following your progressive photos. With that said might I make a couple suggestions?
1: that is a great spot for your LP tank but a bumper is probably a good idea for its protection/a step/tow anchor points.
2: if your planning on a RTT you'll need a couple jacks in the back corners. I put a truck bed camper slide in on my M116 trailer and with two stands in back it was kind of wonky moving around inside. I sold it since. I have two removable jacks (like your tongue jack but round pipe versions) in back but they wiggle just enough that sleeping in it would be maddening. I'm going to make square sleeves from .25" walled tubing similar to a receiver tube. Welded vertical, the jack legs would be something like stop sign posts with a plate as a foot. You drop your tongue jack down, slide in the jack posts with pins, then raise the tongue to level. This way you can relieve your suspension and also use it to remove tires/axle/springs if needed on the trail. I use the jacks when loading ramps are used so the tongue won't flip up, and for the swing out crane operation.
3: Red dog fabricator installed a water tank underneath and between the frame. Pretty slick set up for water.
Keep it up, looks terrific!
