This is all very good and helpful information, Thank you again for your input!!
Small Trailer Update:
While still hunting down Axles & Wheels for the Flatbed trailer, I decided to take the next step and get me the first Tanker for the "B" Double Build to go on with,
Built Box Stock except for moving the axles back a little and up to "lower" the chassis rails a bit....
Not sure whether to make it a Tri-Axle or not, wadda ya think??
