All torsion axled Airstream's came with 22 1/2 degree down angle arms (with the exception of a few smaller late model trailers), however when you order new axles, you can opt for 32 degree down angle for no extra charges. Most of our clients stay with the original down angle, however a few wanted greater ground clearance due to local camping preferences or driveway concerns. Keep in mind that deeper tanks will create other drain plumbing problems so think it all out before making the jump. We've installed a lot of the Vintage Trailer Supply grey tanks, allowing you a flush bellypan, along with the option to add capacity by installing multiples.
