Will a C-Notch put the pumpkin through my bed?

[crakarjax]

Topic sounds funny... anyway I read some guys mention in one thread that with a C-Notch, the top of the pumpkin will hit the bed if you bottom out. Is this true, for a C-20 with a 12-bolt (or for any combo)? I know the C-20 frame is a bit higher so that buys some distance.

While I am on topic, why do a lot of people buy c-notch kits instead of just welding in a pipe section? Seems like a good way to save $80.
