For our build we used pre-painted aluminum, not anodized.
But I did spend a huge amount of time seeking a source for sheets bigger than 4 x 8, we really wanted seamless skin on the sidewalls.
I only found one outfit that seems focused on the auto racing community, selling over-sized painted sheets so people can have seamless skins on their race cars haulers.
In the end we went with smaller sheets and seams.
Big sheets of aluminum are one of those items that industry can get easily for a truckload, but that hobbyists almost can't get at all in small quantities.
Anodize finish is a less common than mill finish or pre-painted so it's probably even harder to find in over-sized sheets.
