If they build it from a 'single wide' stroller, I can see how it would be too small. I used a double-wide. The other thing I did was add the shelf under the handle, it lets me put stuff like my marsh seat and shotguns there instead of up front.
I have a Drake stand up decoy bag filled with decoys laying down in mine in the picture, and another black bag with some decoys laying on top. With bungie cords, I could stack up up pretty high. It doesn't have a tray/sled to putt stuff across the pond, but it's a hell of a lot easier to push/roll all the stuff than hump it on my back plus a couple of shotguns.
Drake bag FYI. To each their own, I guess.
