What model GPS are you using? I can fit the Lowrance 540c in no problem, the 7200c would barely fit with some changes to the dash.
I am assuming that the bigger screen is better. I welcome any comments.
Thanks,
Jeff

The 540 is a 5\" screen and should be plenty big enough. I know the trophy truck and class 1 car guys all like the larger screen but they do a lot more bumping around than we do.

We have a few of the 3500c models and they're the same size. They work great.
