While I can appreciate your concern for saving money, I'd still seriously consider the factory RV units. These would result in a significant labor savings which is something that is of value to someone. I am pretty sure that there are units made that just house the two receptacles with no breakers or pedestal. Those might be worth exploring since I seriously doubt that they cost as much as you were saying.
You have to admit that these will provide you with a much more professional installation as well.
It's like when people say "if you buy $10,000.00 worth of replacement windows, they will pay for themselves within two years". My answer is, OK, how about I pay for them over two years with that savings? If I had a spare $10K, I probably wouldn't be too worried about a few extra bucks a month on my electric bill.
