We have 2015 41' Continental coach. Yes, they are all custom builds, the woodwork is all custom work, they made their own frames, their overall workmanship was among the best. Unfortunately they went out of business like Teton and others. Our rig has an actual weight of 28,000 lbs. At 57' you will definitely need a big tractor and may need special permits due to length to transport the rig. All our plumbing is enclosed in heated compartments. Depending on your intended use this may or may not be a good choice, Best Wishes, Jay
