I have a acua trail houseboat or camp trailer. There were only 38 ever made. You can use it as a camp trailer or houseboat. It has wheels that stay on it. When you get to lake you simply extend the pontoons out. This vessel is 24ft long over all 16ft cabin with 5ft deck on back. Each pontoon is 38in wide it is self contained except someone took toilet out it is 90% there needs to be restored roof does not leak. It has 33 HP Johnsen motor with two fuel tanks this vessel is in good shape just needs some attention there is a video on YouTube about them there is also a web page that tells about them very collectible
I hope it does not leak??
