It looks as if the batteries are the same size. The alternator output on the Pioneer is higher than the Big Red. That being said The battery should be big enough unless you have a large winch and use it a lot. I just installed a plow on my Pioneer and have a 2500# winch installed. I will be watching the battery over the winter to determine how it is holding up. The winch and plow are both made by Warn. The plow fit up is very good it went on just like the instructions said. I modified the Big Red winch mount some and it fit pretty good.
