You're dreaming. But that's what it takes to make innovative strides and eventual success. It's big. It's audacious, and if you science the crap out of this idea, it might just work. Good for you! Do you have a ballpark price estimate yet? Or is it too early?
Crissa is right. At CyberLandr™ we explored a number of trailer/hitch concepts and we stumbled on a few that work well despite the side sails on Cybertruck.
This is a concept worth exploring. Anxious to see a ballpark price.
