Bike Rack / Travel Tray / Sewer Hose Carrier

I want to thank everybody for the good advice. I removed the spare tire from the travel tray and mounted it under the front of the trailer. I moved my sewer hose carrier to the middle of the trailer. I customized my bike rack hitch. Everything works great. I purchased the hardware for the spare tire rack from home depot. It is called unistrut and can be found in the electrical section. I kept the unistrut close together as possible. There is just enough room to get the tire in place. I can remove the tire out easily.
