Heavy Haul Cascadia with 6 speed transmission

[Tagaxle]

Here is my new heavy haul cascadia that I recently finished. We have done several mods to the stock tractor. First of all, the frame was extended to accommodate for the tag axle. The tag is made from a front axle and is liftable with a retract servo. The truck also has a 6 speed transmission. This is achieved by putting a two speed "high low" transmission inline behind the stock transmission. The two speed tranny is from an old king hauler. We decided to go with the 1:1 and 1:4(first and third gear). Second gear gave us overlapping gear ratios. I am running 3 - 2s 4000mah packs in parallel in the sleeper for a total of 12,000 mah. Te trailer is custom made from 1/4 " steel square stock. The gooseneck is removable with functional catch and locking plate system. It uses a waking beam suspension. The tractor has rails for the lowboy to ride on when lifting the trailer off of the ground.
