New toy hauler ramp door!

I know that the repairs and such of ramp doors have been discussed here on this forum but I had an interesting conversation with a gentleman from Challenger Door Co. today. We discussed the purchase price of a new #3000 or #5000 door shipped to my doorstep. The #3000 door is probably standard on most haulers and he said its made with a heavy density foam in the center. The #5000 door is made with alum runners inside the door for strength. He said $1200-1500 for the #3000 door delivered and $1500-1800 for the #5000 door delivered. Both variations in price for each door I'm sure are for the different inside and outside finishes. They have both radius and square tops. From what he told me on the prices, there's no way I would try and tackle the rebuilding of an existing door unless I was bored and for sure had a place to keep in all inside while I worked on it. Just thought is was really a very affordable price for a new ramp door and thought I'd pass that info along. The company is located in Nappanee Indiana.
