This is a few into our tiny home. We have a 2019 Keystone Fuzion 424 Toy Hauler. This is a monster of a trailer and about as big as they come! It is a tri-axel trailer that uses a 5th wheel connection to our truck. It is 44.5 feet long when in ‘travel’ mode and is about 53 feet long when the back porch is out. We choose this model because of the side porch. It is such a unique feature that has so many benefits! With the porch out we are 25 feet wide with the stair out the side.
