The First Step To Take When Designing Your Tiny House Floorplan

Wells let’s just say its the first step after deciding the length of your tiny house 🙂 This would be, where are the fenders located? This greatly affects everything in your design, especially door placements. Below is our master list for fender locations for a majority of our trailer lengths. When it comes to placing your doors in your floor plans, make sure to allow 12″ before and After the fenders for the framing of your walls and the proper hold-downs, this picture shows why that spacing is important.

Where are these fenders located on the Trailer? 

For our Texas, Pennsylvania, And California Manufacturers, the Default Location for the center of the axles is Approx 60% the way back from the front of the main deck, Not including the hitch or Gooseneck. For specific fender locations, Measurement needs to be listed on order. For gooseneck trailers, the measurements below would be for the lower deck of the gooseneck trailer.

20ft deck = Approx 12ft Back from the front of the deck to the center of the axles

20ft Trailer is 240 inches in length (20ft x 12in = 240) 240 x 60% = 144″ (center of fenders) – 36″ to find front of fender location = 108″. 108″ from front of deck to front of fenders, add the total length of fenders back in (72inches) to 108″ = 190″ from front of trailer to rear of fenders. Take 240″ for total length of trailer, minus 190″ and that leaves 50″ which is the deck space behind the rear fender to rear of trailer.
