Below is a list of things I do not think are needed in a conversion. Some people will disagree with items listed. The reason for writing this is to stimulate the conversation. Some of the items listed will not be practical for your conversion. I did a DIY on a 08 Sprinter that I sold and now am starting on a Transit. Have about 100 changes from the Sprinter based on what I learned. Sprinter worked very well and the floor plan is the same. Some items will not apply for your location and weather. I am writing this list based on my use of the van. Will not be appropriate for everyone.
1. Multiple solar panels. A single 300 watt panel will work very well.
2. 30 amp shore power plug. If you do not have air conditioning why is 30 amps required. Add up your loads. I have used a 13 amp reel on the Sprinter and never had a need for more amperage.
3. Multiple batteries. One 8D 255 amp-hr battery worked fine for my application. Simplifies the cables.
4. Outdoor shower. With a little effort a indoor shower lets you shower anywhere. The trick is to use the shower space for multiple uses. I have a shower, a portapotti, a food storage bin, a towel rack and a countertop located in the shower enclosure. Just remove stuff when you want to shower.
5. Sink and Shower drain traps. If you plumb the gray water tank so drains enter the bottom center of the tank, a "trap" is created in the piping. I just use 1" coolant hoses for piping.
6. AC distribution panel. Had one in the Sprinter but will eliminate it in the Transit. One circuit breaker for one circuit with 5 duplex outlets.
7. Fancy thermal and privacy curtains. If you look at the Transit windows, they have a slot between the glass and the interior steel framework. A Reflectix panel covering the glass will slip into the slot with a tab to hold it in place. (I only have the slider and back door windows) Cut Reflectix to cover window with tabs to insert into the slots. Taped edges with Reflectix tape. Super easy to install and remove.
8. Large Microwave. A cheap ($50) 600 watt microwave from K-Mart (Proctor-Silex) works fine with a 1000 watt house inverter. Simple mechanical dials and no clock or pushbuttons.
9. Normal mattress. We use two REI 2 1/2" camp pads for each person. Easy to remove and store and comfortable.
10. Expensive complicated shower hot water heater. A 5-6 gallon tank with a 625 watt pencil heater will heat the water to 90 degrees in 30 minutes. You need a 1000 watt inverter powered by the Transit while driving to get the 120 volt power. The heating element with a thermostat is sold as a conversion kit for RV's with propane heaters. A tank, the kit, a submercible pump, a garden hose and a garden nozzle completes the system. All water is at the correct temperature so no hot/cold water mixing required that wastes water.
11. 2000+ watt house inverter. A 1000 watt inverter covers my requirements and will run a microwave.
12. Noisy large water pump. I had one in the Sprinter and did not like the noise and large space requirement. Transit will have a very small solar centrifugal water pump mounted at the back of the slider step. Turn it on when you want sink water. Plumbing will have a small bypass from pump outlet back to the fresh water tank. Bypass needed if I forget to turn off the pump to prevent it from getting hot. Pump is quiet so you can not hear it running.
13. Complicated plumbing. With the simple water heater eliminating shower water plumbing, the plumbing will have a gravity drain to a centrifugal pump with 3 outlets. One to the sink, one bypass to the fresh water tank and one to a ball valve drain. Pressurized water is available at the drain with pump is running.
14. Shower sink. A waste of space. Shower enclosure needs to be use for multiple purposes. I use a Folgers instant coffee jar when brushing my teeth because I do not want to use the kitchen sink for that purpose.
15. Doors on overhead cabinets. A shelf with a 3" high rail used with baskets makes for a simple solution. No doors to get in the way, less weight, less cost, and easier access to the contents. Worked well in the Sprinter.
16. Clothes closet. I installed a handle on the back side of the refrigerator cabinet so clothes could be stored on the side of the refrigerator cabinet.
17. Large number of lighting switches. Buy LED lights that include a switch. Just turn on the light you need at the light.
18. Air conditioning. People in mild climates can use natural draft air movement. A 4" x 4" hole in the floor and an open roof vent will create air flow from under van and out the rood vent. Movable cover is required to close floor vent when required.
19. Awning. How often will you use it? I can not have one because I stealth camp in cities. Many who have awnings seldom use them.
20. Built in counter top stove. Counter top space is limited in a small conversion. A portable propane stove can be used inside or on a picnic table or in my case on a drop down table out the sliding door.
21. Interior heater. I have found that a 12 volt heating pad under my sleeping bag keeps me warm at night. A balaclava keeps my head warm. Van is quiet without a heater running and the refrigerator runs less due to the cold van interior. Electrical use is about the same because refrigerator runs less.
22. Van wall mounted shore connection. A molded male end of a 12/3 extension cord that is tucked up under driver door works well for 15 amp service.
23. Fresh water level detection. With the right plumbing design a piece of clear tubing from pump located below the tank to the sink will show how much water you have in the tank.
24. Heated water tanks. Put fresh water inside and gray water under van. If it gets cold dump the gray water tank.
25. Sink hot water. Wash dishes with cold water and soap.
26. Mirror. Mount the microwave door high so door glass acts as a mirror.
27. High amperage solar controller. I have found a 15 amp MPPT controller will maintain my 255 amp-hr battery. Even if it could provide more than 15 amps, that would only occur around noon. Very little charging lost if the top of the charging curve mountain is flat.
28. BBQ. I will use a cast iron grill on top of my Camp Chief two burner stove. 17,000 BTU stove burners are much better than 10,000 BTU burners.
29. Black water, macerator, hose etc. A simple portapotti is easier to deal with than a built in toilet. Quick food places were invented for facilities not for food quality.
30. Direct charging of house battery from alternator. Does not give a correct 3 stage charge to the house battery. A vehicle powered inverter supplying 120 volt power to your house battery charger will.
31. Conduit and wire. It is much easier to use "SO" rubber cords for wiring. Cord can be bent in a tighter radius and is much easier to install.
32. Do not bury wiring in wall. Depending on your cabinets, it is possible to locate wiring outside the wall behind cabinets for future access or additions. I do have a 1 1/2" thick insulated floor that allows cable to cross from one side of van to the other in the floor. I do bury 16/2 lighting wiring in the ceiling.
33. Ford wire trough. A simpler replacement with easy access is a Panduit or equal control panel wiring trough. Easy snap on/off cover.
Do not expect everyone to agree to this list but it should provide for some discussion. Hopefully others will add to the list with their discoveries.
