My family likes to go camping, and we prefer tenting for several reasons. However, it was a pain to load and unload the truck, then find somewhere to store everything when home.
So, last year I built a trailer to tote all our stuff, and make camping much more comfortable. It has a 50-gallon water tank, 12v battery, pump and lights, propane tanks, and a water heater. There is a connection for hoses to run water to our shower tent, and we now have hot showers!
I put the springs over the axle, for better clearance, as the places we camp tend to be at the end of rough dirt roads.
The kitchen is the old Boy Scout patrol box type, which is removed and set up where needed. There is storage behind the rear door for the porta potty, and the turtle top is for sleeping bags and other light-but-bulky items.
After using it several times and finding areas to improve, and looking around these forums, I have drawn up a plan for a new trailer. The body will be wider, with the tires inside it, instead of on the sides.
Some areas do not allow water to drain onto the ground, so the shower needs to be better than a tent: it is now in the trailer, in an area based on the Wild Goose/Kampmaster trailer idea. This will keep the plumbing simple, and will include a cassette toilet (hard to find in the US). The light-but-bulky items will be stored here, too.
The typical teardrop galley in the back will save having to unload all the kitchen supplies, but has been modified to provide more space. The lower cabinets will swing out, making access easy and creating a very wide countertop. A faucet will be installed there, too.
A large compartment in the middle will be storage for folding chairs, camopies, etc. A 100-gallon water tank sits over the axle, but the propane tank has yet to find a home, since the shower door taes up the tongue area.
Looked into an instantaneous water heater, but at $1,000, I'll stick with a 6-gallon tank-type for less than 1/3 the price.
The drawings below are what I have so far, and are far from being ready to build from. If any of you experienced folks have any suggestions, fire away.
