HELLOOOOOO!!!!
WOW, I don't know where to begin... 1st... don't get a bed put above the cab... you might as well get a hammer and bang it against your head. You get the same effect. and it costs less.
The bathroom on that rig was THE BEST. Really, the only good thing about that rig was the plumbing set-up.
if somebody alot more computer literate than me should cut and past (somehow) a pic of just the bathroom and view looking at the fridge on here that would be awesome.
You see in those pics the counter on the right next to the small very uncomfortable sofa... well there was a sink there, and about 12"+ of counter space. under that sink was a 5 gallon HOME hot water heater. That bad boy was awesome! I could take a 15 minute HOT shower in there. The water would heat in about an hour. There was a timer on the wall for the H2O heater, but it began to give us trouble, like sparks. So, we disconnected it and just had it so the switch on the back wall turned on/off the inverter. Then that blew somehow, so we just had to lift up the sofa and turn on the inverter, and then plug in the hot water heater... unplugging it when we got out of the shower. 2 people could take 2 good showers in that truck in less than 1.5 hours. (2 people can also take a shower at once to save time, smile). I know because I had a g/f on the rig with me for a month. The shower was 24" x 24". Don't mount a cabinet down too low on the wall to the left of the toilet unless you want a concussion... seriously.
Regarding the water issue... on custom busses, what we do (sometimes) is pipe the grey and blackwater into one tank - to save space (and dump time).
There was a 40 gallon freshwater tank on there, I'd go with atleast a 60 gallon freshwater tank.
Be sure to get heat strips for it, or it will freeze. Put insulated material of some kind in next to/around that freshwater tank. 40 gallons will take you about 5 days, you can stretch it to 7 days if your real careful. Thats why I say go with 60 gallons freshwater. You'll need a monster power inverter too, the 1500 watt one is what was in there I think.
I would never, you all hear me, NEVER EVER EVER, sleep in a bed above a cab in a sleeper anywhere similar to that again.
Don't do it, that sleeper was 96" plus 54" above the cab. Technically though there was really only about 40" of actual sleeping space. The window was great, in warm weather. in COLD weather it was COLD UP THERE. Don't put a window up there, it looks pretty, it's pretty to look at, so long as the rig was in temps. above 65 degrees. That sleeping space is tough to heat up there, and even tougher to get cool up there. Hot air rises, cool air does not.
I could go on and on and on about that rig. Thats my 2 cents there so far, let me know if I can offer any more advice.
Easy solution to that sleeper,
Remove the window above the cab, it's just loosing heat/cool air out of your sleeper. Use that space for storage and electronics.
Remove the side entry door, move the bathroom forward, and the fridge over onto the right or left side, and put your bunk across the back wall like a normal rig.
if you decide to sleep above a cab, do you know it's illegal in most states to do so while the vehicle is in motion?
just thought I'd mention that too. Not to mention it's just dangerous in general if you roll the rig.
Let me know if I can offer more advice/tips on sleepers like
"The Freaky Freightliner" had.
