Building a car trailer from an RV frame is not as difficult as it seems. There are a few things that you will need in order to make this process easier. The first thing that you will need is a frame. This frame can be found at most hardware stores. The second thing that you will need is a truck or SUV. This vehicle can be used to transport the trailer around. The third thing that you will need is some supplies. These supplies can include nails, screws, and wood glue. Once you have these supplies, it is time to begin the process of building your car trailer from an RV frame. The first step in this process is to measure the length of your RV frame. This measurement will help you determine the size of your truck or SUV that you will need to transport your trailer around on. Next, cut out the necessary space for your car trailer on your RV frame. This space should be large enough for both the car and the Trailer hitch connection. Once the space has been cut out, it is time to start construction of your car trailer from an RV frame. The next step in this process is to use some wood glue and nails to attach the two pieces of your RV frame together. Once these connections have been made, it is time to start attaching other pieces of your car trailer onto thisframe using wood screws and nails. Once all of these connections have been made, it is time to finish up by attaching any final accessories onto your car trailer using wood screws and nails
