I would take what Tom says with a grain of salt. Just about all the top RV manufactures use a box frame for strength and have been for years. I don't want my frame to "flex" and ask Tom to prove a I beam frame is stronger than a box frame. I can't ever remember reading about any box frame RV that the frame has rusted from the inside out and destroyed a frame. He tried to tell Crossroads owners that cutting the warranty in half from 2 years to 1 year would be better for the customer and got his tail torn up on the forum. I would think the market for high end expensive 5th wheels would be fairly small with the economy failing and fuel prices on the rise again.
