Marine battery as starting battery

Hiya all,

Walmart is selling a Huge marine battery for $64.99. I am looking to replace
my regular starting battery with this one so I can provide power to a camper
shell and also provide for starting. I think I can get it to fit . There is
no room in the engine bay for
a second battery and the camper has no battery of its own.   The specs of
the battery : 675 Cold cranking amps - 205 minutes reserve capacity. Will
this battery start the engine in my pickup truck, even under extreme
conditions?

1993 F150 , 4.9 six cyl .
