I wouldn't expect to be bad. I bought my 200 gallon tank and stand from a hillbilly in Alabama, and I live in Georgia. He said he left it on his porch for two years, where it was exposed to all weather. Before that he managed to keep the basically one ton aquarium inside of his trailer with him later stating that the floor didn't sag (I almost told him to check again). When I got it back to clean it and test for leaks, it held up.
