Unfortunately rear bar will need to go on top of rear of portion of ac cover. Canoes need to sit on top of ac unit a bit or they will hang over the side of camper. Planning to replace plastic cover with custom aluminum that can support center of bar. End supports for bars will be raised 1a towers bolted thru.
Front cross bar will go somewhere on main roof a foot or so back from the beginning of sloped front section.
Plan to set rear of canoes on top ac, front onto std height bar with the 1a towers which is around 7 inch high.
Yep i crazy. Yep i have a system to get the canoes up easily. Total canoe weight could be as high as 150# and up to 16'-6" long
Need 5/16 holes. 2 at end of each rack. so two holes for drivers side front mount back from front cap, 2 holes drivers side in line with rear of ac unit, repeat on psgr side.
Also need one hole in center Left to Right for front bar a foot or so back from sloped front cap. Need this to support the span. I think. Bigfoot bars are 8'-6" long and BF bars will be shorter but still think i need to support center of front bar.
Anyone drill thru a roof?
how thick is roof - top to interior?
Frame locations? or even a guess

Wires? do not think there is much. fan and ac is all that is up there.
I had a diagram for Bigfoot and did not hit any frame or wires.
Attached a pic of our Bigfoot set up for reference.
Thanks for any help. And anyone have a 24RB they want to sell?
