The following is a build I put together with a Vagabond Drifter Camper (mostly copied from a thread on Tacomaworld.com). I picked up the Drifter back in February 2019 and worked on it mostly in the spring and early summer.
I bought a the truck mainly for the camper in August 2018:
I worked through various concepts in sketchup... it ended up not being particularly helpful but I had a while to wait before the camper was ready:
My plan for the build was to make everything as portable and removable as possible while still providing space for electrical and mechanical as well as a bed platform for the kids. The hope was to fit a family of four somewhat comfortably in the camper. Whether that will be a success is to be determined but it has worked really well so far. I settled on a mixture of built-ins and removable bins to allow for the space inside for four people. The bins can come out to make room for sleep or stay in if I'm solo or just with my wife.
When I started the auxiliary battery system, I really wanted to stuff the battery somewhere under the truck bed. However, there wasn't much room so I settled on a homemade portable battery box. I found a renogy 100ah gel battery on craigslist for $100 and got a 30a DC-DC charger on amazon warehouse deal for $105. I ran wire from my starter battery to the charger. I put a fuse block and some connectors on the box. The charger is also an MPPT solar capable so I wired a sae plug for a future panel. I eventually ditched the tool box enclosure but kept the portability by wiring in quick disconnects. The wire to the starter battery connects to the auxiliary battery via and anderson plug. The solar panel and Drifter switch panel connect via sae connectors.
After I got the camper, I installed a flexible solar panel. I used adhesive backed velcro to fasten the panel to the roof and ran a strip of duck tape around the lip. After a few months of snow/sun, it seems to be holding up well. I didn't like the idea of fighting with vhb tape if I ever needed to remove the panel:
I installed an awning on the back of the camper:
I ordered a bunch of 30mm aluminum extrusion and started working on a built in cabinet. The point of the cabinet is to house the electrical/heater/water/fridge and provide a platform and some additional storage. It was my first time working with the t-slot extrusion but it was pretty straight forward. I put the cabinet together with a fridge slide. The slide shelf is temporary until I figure out how I want to do a nested drawer. I think I'm going to do a pullout sink with a faucet. The kids approved of the bed platform.
I ordered a webasto diesel heater. I went with the webasto for the easy high altitude adjustment being in Colorado. I bench tested it, cut a whole in the truck bed and mounted it. The heater is really the only thing that will not be easily removable. I had a shop install and auxiliary fuel tap in my tank to supply diesel to the heater:
The portable battery box ended up being more bulky than I wanted so I built a small platform for the battery to sit above the heater:
At this point, the build looks really simple but mostly accomplishes what I wanted it to do. The main cabinet is bolted to the floor with two bolts so it is really easy to remove. The battery box is fastened to the floor via tie downs and straps. The platform across the truck bed is independently removable so I can still transport large items:
Easily my favorite part, not counting the camper itself, is the diesel heater. Being able to keep myself and four year old comfortable with lows in the 20s.
I carpeted the side wall panels. I ended up ordering a generic Bedrug mat. It was a little pricier than just using automotive carpet but it was really easy to work with. It has ~1/2in foam backing and I was able to attach adhesive velcro so they are easily removable. It's strong enough to hold small velcro organizers. I haven't done any rough roads with them so we'll see how well they actually hold.
The stock dome light always bothered me. I did led strip lights all the way around on a dimmer. The strip lights are mounted inside an aluminum channel with a diffuser. I have the dimmer wired downstream of a switch so you can set the brightness and keep it there. The interior lights are wired to a new switch on the stock panel and I donated the existing light switch to the exterior lights. The strip provides really even light over the tailgate.
I found a mattress on amazon that fit the space perfectly so I don't need to get custom cushions made. It has a waterproof cover which is good for kids.
I put mini d-rings all over the extrusion so I can use bungees to hold stuff.
Finally put sheets on the mattress. I'm usually in a sleeping bag but now with the heater I'll probably switch to a blanket so the sheets will be nice.
It's packed up for a trip down south so it'll be interesting to see how warm weather camping goes... glad I have the fan.
