I liked your truck very much and I have to give credit where it is dew. here you can see my redesign / rebuild based or heavily influenced from your concept. after testing there were a few things that I wanted to address. First MOLAB got unstable even on Kerbin with the higher gravity (the roll lags did stop this most of the time) #2 MOLAB broke easier then what I wanted. After all I may need to let Bob drive it if push comes to shove. #3 MOLAB's solar panel power. I could not see truly powering a mobile base on solar and going dead at night, so I went nuke. left the solar panels cause they look cool, and would provide shade for the work deck. I can provide any info anyone would like just message me.
