I'm building a mowing trailer for my grandson and I'm wondering if anybody has any suggestions as to what could/should be added before I start sheeting it up. It carries 3 catchers in the front section, 2 mowers and 2 whipper snippers in the main section, has a shelf for odds and sods, oil,rags, funnel etc. He wants a couple of jerry cans fitted on the outside but I'm not sure if that is a good idea because they would be exposed to the sun unless I built a cover over them. Open to any suggestions.
