Thank you, Paul.
Your kind offer duly noted, sir.
Serenity* is closer to sea-worthiness. 100w solar array, dual tanks up front. Honda Genny to be mounted on rear 2" receiver, somehow. Loadmaster says 100# hanging off the rear is a significant consideration. So no bikes.
Torsion axle is much like the trailing arm on a 911. The wheels do not go straight up and down. They travel in an arc. Upgraded axle will be mounted slightly forward to accommodate larger wheels and tougher tires. When fully compressed they should fit right inside the wheel wells. The axle is also adjustable. I'm starting at the usual start angle of 22 degrees down. Storm case will act as a step for ingress (not shown):
