There is something else I consistently carry to the field besides the backpack that holds my paints. This child-sized steel folding chair is surprisingly lightweight and actually small, 33" long by 12" wide. I usually strap it to a handcart without any problem.
I decided that If I am going to go through the trouble of creating a custom cart, that this cart should also carry the chair. The easel and the chair actually fit together quite well. The whole package is 12" wide, six inches deep, and 39" long.
After some research online, I also decided that a wagon would not do, due to the fact that I often have to go up and down stairs in my search for suitable painting spots. Hand carts are also quieter and much lighter in weight if made with the right materials. Wagons and bike trailers online looked attractive, but were too expensive and not really what I needed.
Here I should add that I have weak hands and the thought of tying bungee cords brings pain to my senses. I decided that this cart should help me do away with the need for bungee cords.
Burley Travoy? Two reasons: The handle system in this hand cart/bike trailer not really made for long treks on foot. And, although the Travoy sports an award-winning design, it requires securing the load with...you guessed it, straps.
I did like the 12" wheels on the Travoy, so I decided that this would be the type and size of wheel I would use on my custom cart.
