I looked at some ready made alternatives and didn't like the weight or the price
and any m416 I could find was beat to death.
so I decided to build a dinoot J-series trailer.
Making the floor.. I went ahead and double sided the entire floor where the plans
only doubled some parts of the floor. Since you have to buy two sheets anyway
and I was able to do that without any extra marine plywood. Due to adding a box,
water tank and battery I move the axle a little forward of the plans
