Just got back from the dealer, and my new Bike Rack/Cargo Tray is now installed on my Eagle! As expected, it took about three hours. It's quite heavy duty (except for the plastic floor), and looks like it should carry the items I mentioned in an earlier post. I did manage to find a weight load capacity for it - 250 lbs.
Thanks, again, to everyone who contributed their input. Really helped me make a decision I'm sure I'll be happy with.
