Toy Hauler Information Overload! HELP!

Go to featherlite and request a trailer designed for your racing needs and the number of people it will accommodate. Do not forget to take into consideration the type of roads leading to the tracks. It will also require a serious tow vehicle. According to the needs you specified this is your best route as TH are designed for campers not racers with spare parts, tool boxes and other heavy items. It will cost a little more but will be a much more satisfying racing experience.
There are. Others that will build race trailers but in my opinion they are by far the best.

Happy camping
