1988 Airstream Excella that has been retrofitted for business use. Inside has been fully redone to accommodate six small desks as seen in the pictures. Outside logos are vinyl and can easily be removed. Unit is equipment with both heat and A/C which runs off the generated on the back of the unit in a diamond plated storage unit. Generator comes with the Airstream as well. Paperwork for all work done to the inside of the trailer I do have records of. States the unit is the Excella Model based on VIN but unsure if it is the 500, 1000, or Limited.
