One thing different about this design from most of the others is that I opted to leave the kitchen open to the inside of the bed area. While this sacrifices the storage of overhead cabinets, it means that you can access the sink while inside. During bad weather, it's pretty nice to be able to wash your face, brush teeth, etc without having to go outside. The sink has hot and cold water, though it is designed such that the rear hatch has to be open if you are using the water heater. There is a hatch under the end of the mattress that provides plenty of storage space for kitchen ware. We use a two burner camp stove on the kitchen counter left of the sink or we put it on a table to cook. There is a propane tank in the tongue box with a gas line to the back of the trailer which has a camp stove connection and also feeds the on demand water heater.
This picture shows a close up of the water heater. I cut a hole in the side of the trailer and installed a deck plate with a lid that easily unscrews to reveal the water heater controls. This is right next to the shower wand, so you can control the temperature of the water for a shower. We have one of those shower privy popup things so you can set it up next to the trailer for a hot shower. With 36 gallons of water capacity, two people can take hot showers daily over a weekend trip and still have plenty left over for rinsing dishes and other uses.
In my original design, the mattress was on the floor of the camper which means that the mattress had to be notched around the wheel wells. The camper fits a queen mattress, though it was more like the width of a full at the narrow point between the wheel wells. I designed the wheel wells into the camper so that the trailer's axle width could exactly match my Land Cruise 80 - a design element that proved to be incredibly convenient when towing over rough terrain or along a rutted trail because the trailer follows the vehicle path very closely. Eventually I decided to build a platform to raise the mattress above the height of the wheel wells. This caused a decrease in head room, though you can still sit up inside. The benefit of all of the storage under the mattress is great. This picture shows the space where I store an easy-up, chairs, the shower privy, a mojo griddle, etc. There is also space for more water tanks if you wanted to have the option to fill tanks that are insulated for winter use The current water tanks are exposed to the outside and would freeze in winter, but tanks under the mattress would solve that problem and could add even more water capacity if it even became necessary.
