A "large", yes. An "extra large" would be too big.
I've also carried at different times:
2 30-packs of beer.
3 gallons of paint.
A flag and flagpole kit - the kind that mounts on a wall - about 3 foot long in the package.
A buckhorn handlebar.
And finally, a tupperware container full of a dessert called striped delight, which is made with pudding, cream cheese, and Coolwhip. It was more like a soup by the time I reached my destination....
