Tow your Travel Trailer and take your boat

Last year i moved from a truck camper to a trailer. I had to figure out how to take a boat with me as i almost always go camping at lakes and i like to explore and go fishing. I downsized my boat, but still needed a way of transporting it. This is my idea i came up with. I made this boat loader using some purchased retail items and customized it to load & unload my boat without any help from friends or wife. I filmed the loading and unloading process, let me know what you think!
Link is for my youtube video. Home made boat loader

Cost me about $500

So far i have used it about 10 times, and i am going to add one thing to it. Some plates on the outside of the rollers that will come up higher then the roller so there is no way the boat can slide off the side when loading/unloading.
