Toy Hauler/Camper Research and build

Hey everyone,
I'm looking to build a toy hauler/camper and have spent many an hour drooling over the masterpieces that have been build. But I still have some questions. This is going to be a combination of hauling the bikes to the track, and then sleeping in the trailer. Most of our riding is in the south, so air conditioning is more important than heat. Also want to add a small toilet. So some of the questions I have are as follows.
I have seen where people have bought the trailer with an extended hitch frame, was this for better control towing on the road, or just more space to store fuel tanks, or gas tanks up front of the trailer?
Have any of you built for hauling motorcycles, and do you have suggestions on what worked, or what you would change? We will be hauling three, maybe four bikes, so what width worked for you? Can we get three across, or only two?
That's all for now.
Thanks
