Brewer has this to say about his friend Mark's truck:
is a '92 GMC Topkick which did duty for Ryder in it's previous
form. The truck was rebuilt from the ground up. The frame was
shortened 10ft (Yes ft). Grafted the extended cab on it from a
late model and added 6 extra inches in the middle. It retained
the front stock suspension but used a air ride rear from a Freightliner.
It has a 290HP cat in front of an Allison 4 speed auto trans.
Nothing about this truck is standard as even the engine was changed
out having been a gas engine. The interior is very plush with
pretty much everything power. It took about 8 mo. for us to complete
this truck and everything was done in house including paint. Nobody
could figure out what the hell we were building during the construction
but it turns more heads than you can imagine.
