I have a ruffland and a Dakota 283, both are great portable crates. The Dakota is significantly more stout than the Ruffland, and not that much heavier. The Dakota also has a drain that makes it easier to wash out the crate. The ruffland "either way" opening door while not as solid is nice.
For similar pricing the Dakota is by far my favorite.
I have a buddy who won a gunner, he says every gunner should come with a forklift.... He leaves it in the basement
