Always wanted to raise the roof and put a bed over the cab, the first one I saw was the e350 bigfoot hunter on "Rock my RV", then i just found this guys on craigslist(too expensive for me and half the fun is the build):
http://tampa.craigslist.org/pnl/rvs/5677811491.html
2003 Ford E350 with McCoy Miller ambulance body.
7.3L Powerstroke Diesel with 390,xxx miles on it.
The ambulance body is all aluminum with stainless steel hardware.
The entire exterior of the rig was paint with Al's Liner heat and noise reduce, then 8 gallons of bedliner.
Three windows were added bring the total to six plus the two van windows.
The interior was fully gutted, all insulation and electrical removed.
The roof was cut off and raised a foot in the rear and two feet in the front. Interior height inside goes from 77" to 89".
A bed was added over the cab that holds a full size mattress and has under bed storage.
All new 110 volt and 12 volt electrical was run.
Fiberglass insulation was added to all walls and ceiling.
Ceiling panels and walls were made from 1/4 underlayment, carpet padding, and grey vinyl.
Custom cabinets built from 3/4 sand ply and select pine used for door frames.
Kitchen has a tiled backsplash and a sink with a washboard.
Plenty of interior and exterior cabinet storage.
TV with Sony Blue Ray Surround Sound system in the main area.
TV with Blue Ray DVD player in the bed area.
Frigidaire 4.5 Cu Ft refrigerator and a microwave.
LG window shaker for A/C.
Under cabinet lighting and an LED flood light above outside door.
All exterior cabinets are diamond plate except for one.
All exterior cabinets are lockable and have 12 volt lighting.
There is a 16 gallon fresh water tank and a 16 gallon grey water tank.
It is plumbed for city water or potable water.
Power supplied via shore power or an Airpax 1800 watt pure sine wave inverter
Currently has one house battery since we never boondock.
Installed an Automatic Transfer Switch so I would not have to manually switch between shore and inverter power.
Two inch leveling lift installed in the front to allow for 235/85/16 BFG Rugged Trail tires.
Custom built rear bumper houses the spare tire and grill.
The grill is mounted in an Army medial box on a draw slide as well as a swinging arm. This allows you to rotate the grill parallel to the passenger side of the rig so you can socialize while grilling.
HID headlights and billet grille in the front.
Brand new steering box just installed along with all new ball joints and tie rod ends two years ago.
The entire interior of the van cab was insulated with DynaMat.
The grey leather front seats were purchased of Ebay brand new from a 2012 Nissan van.
