As I near completion of my M416 type trailer, I am looking for a stabilizer jack arrangement for the rear of the trailer. I have a demountable front tongue jack, 38 gallon watertank under the bed, and dual 105 AH deep draw batteries, pump, charger, and invertor in a tongue tool box. I should balance out right according to my calculations. I would like to install a swing down or detachable stabilizer for the rear, so that additional weight on the tail gate won't cause problems. Suggestions??
