Front mount receiver for E-450
This ebay ad says they have a Drawtite front-mount hitch for your E-450. I was surprised that eTrailer.com doesn't include E-series for any of their front-mount hitches. However, further snooping on the Drawtite link below, I see the part number is 65001. And search on eTrailer for part number 65001, I found that hitch available from eTrailer at a good price.
Here is a link to that DrawTite receiver on the manufacturer's website (Horizion Brands). Scroll down to the "this product fits" area and note it fits the E-450.
Here's a link to that hitch from eTrailer.com. I personally prefer to order from eTrailer than from an ebay source.
