Forward Air is great for large items.  The are, by far, the least expensive
(as long as there is a terminal nearby).

HOWEVER....  make sure your items are packed very well.  The guys who
operate the forklifts are animals, and the packages are moved around quite a
bit.  I've sent many large items via Forward Air and have learned this
lesson very well.
