They go backwards to keep more weight in the back (side facing up hill) and helps prevent tipping over or catching the bucket and flipping.Easily got my thumbs up. Nicely presented video and down-to-earth narrations. No stupid music and we actually got to hear the original sounds of the clips! Thank you!Like with most of the youtube compilation videos the narration is the low point. This video would have been much better without any narration.In our place all heavy trucks modified to have water tank to drip the brakes to keep it from overheating. Especially in hilly roads as most our roads.
