Full frame Dump trailer build ?

[Lmackattack]

I need some insite on how you guys have built up a operational end dump.

I'm starting with rails and axles from a tamiya flat bed. The box will be from the flat bed parts and some aluminum sheet stock.

My question is more to the mechanical parts


1. what type of screwdriver,pto,pump etc....is best used to lift this thing when loaded with dirt or sand. Cost and simplisity is a factor.

2. Will I need a 2nd battery to operate a pump or lift?



Any tips are helpful


Thanks for looking
