I think the quality was what I expected. The composite panels felt sturdy and there was no spongy feeling when pressing against the surface. The seams all looked to be well sealed. The plywood looked to be marine quality as advertised and I did not see any voids on the edges. One disappointment was there was no finish work done to the edges so it was very rough to the touch. If I buy a Kenai, I will definitely sand all the edges smooth and apply wipe on polyurethane. The grey veneer will show dents and scratches easily so I would have preferred a more natural surface but both of those issues would add to the production cost. The inside the cabinets are exposed obviously and also have an unfinished look to me but overall what I would expect.
I think the structure would hold up well to abuse and they will hold their value well because there is so little to go wrong with the minimalist design.
Overall I think this is a great product for a lot of people. For me, it comes close meeting all my needs but I'm concerned with the east west bed, small dinette and the water capacity.
