After seeing yours i thought i would build one as i have limited room in my garage,
i have to push the car fwd to clear the roof trusses

now i get an extra meter by pushing the car on way or the other ( the rotisserie is on wheels )

even the cat think it's great
if i look at this one too long i get vertigo
the hardest bit was making the brackets to fit the vehicle
at the front i used the hinge mount bolt holes plus welded a bracket around the side to fit where the front end bolts on
the rear is bolted to the bumper mount
