I like the Lance and I'm still kicking my backside for not going with it over a Dutchmen.
Go to the Lance web site and look at their video on the manufacturing process, then go look at the others and compare.
One thing that stands out in my mind is how they make up their wiring harnesses. They actually do make a wiring harness that is consistent for the model. Ducthmens wiring harness is about this much wire should do, if you got too much just shove it behind something and carry on. I have found wires the were pinched under cabinets, rubbing on the fridge frame, etc. after I got through cleaning up the wiring, I had close to ten pounds of surplus wire, I got $2.50 a pound for it at the scrap yard. That ten pounds of wire cost me probably $100 or more in the price of the camper.
