The engine has already gotten narrower. That photo was after losing 40 lbs the first year commuting (1450 miles that year).
I'm going to try building a trailer that will accommodate the table laid flat. Wind can be a big issue here in TX.
I may give this one a try
(Mother Earth News Plans), but it may be a bit too tall and heavy (lots of wood). OTOH, it should be easily adapted size wise.
The table DOES have its own case to protect it and pockets for supplies built in.
