Yes towers are floor, they are a little high yet maybe 1/4". Left some material to be able to tie into body structure. Plenty of height. Oil tank is going to be same as 1:1, side tank. I could put valve body or esc in other side tank but both of them have a lot of wires/hoses to rout so not the best location. I was going to put a radiator fan (computer fan) in this but in reality I have one in both the dozer and excavator and have never had a need for it. Never overheated anything even in hot summer. I'm building the belly pan now. I am trying to do a magnetic front grill that will give a lot of access to battery and electronics by simply removing. Lights are in bumper and higher up on sides. Grill is only problematic because a ladder diagonals it. I'll probably just have it permanently attached so just one unit (the black part of grill and ladder in front) are held on with magnets. Simply pop off install battery and pop back on. Sounds good so far, I'm sure some challenges await
