Hmm...I found this pic somewhere and just figured it might be typical of a double cabin eagle cabin top. I'm building an XL but will go with full width cabin, hence my question. Could you please say what dimensions are called out ( diameter and thickness ) on your plans for the front and rear cabin top tubes?Several others have recently indicated they're building XL's with a full width cabin and if they'd like to chime in with some tubing references that would be a good thing. Thanks...
