Custom Floor Mats
I picked up a set at "high-end-motorsports" online. The set I got was listed as
"High-End Quality Ford E-450 Super Duty All-Weather Custom Floor Mats in your choice of 8 colors to match any interior.
Protect your Ford E-450 Super Duty in Style. Proudly install a set of Exact Fitting All-Weather Floor Mats, factory compatible anchoring devices or easy to use fasteners. Custom fitted for your vehicle and manufactured by Lloyd Mats™. Each Rubbertite™ mat has hundreds of "Wells" that hold water, snow, mud, sand and spills. Each "Well" is rounded so the dirt just hoses clean. This heavy-weight composition rubber mat will stay flexible in sub-freezing temperatures. Plus a non-slip texture surface for additional safety and performance along with nibbed backing and fastening to prevent sliding. These mats are attractive, feature a Contemporary Edge to Edge design that an Ford E-450 Super Duty should have! "
It was $59.95 and they look and fit awesome. The 3050S is my wife's pride and joy, so if she likes them then they have to be awesome. I got the "Slim Line Console W/Dual Storage" option, as you have two types to pick from. these fit perfect.
Just my personal experience, no trimming, no cutting, just lay them down and get to camping.
