So reading the link Patric provided it sounds like Mansion really missed the mark and told the designers there are major changes in the design after the original design and haven't paid for the original design. It just sounds like Mansion is flying by the seat of their pants, and they haven't really done the research into the infrastructure for the site. It sounds like on just the RV park site they blew the design by making all the spaces 80' spots and having to go back and cut a number of the spaces to 40' but keeping the same number of spaces. I would think this is going to limit the number of big RV's with trailers and even smaller RV's pulling trailers. I'm just looking at this from what I have seen over the years of RV traffic around Arizona. A 30' fifth wheel being towed by a 1 ton crew cab pickup won't fit a 40' space, nor will a 30' or 35' RV towing a vehicle.
It's not uncommon to see this type of RV here especially around Lake Havasu, Roosevelt, Pleasant or Powell.
With Oologah, Hudson and Grand just a short distance away, I would think that there needs to be space for set ups like this.
