tinnyjinny, i believe you will find that 2225 is your vin number. my 1969 travelux is ser 6119, found on closet door, as yours is. when you need to get an ownership, DO NOT go to any government contractor office (eg like "service" ontario) as some have no clue what they are doing. go to a real government drivers and vehicles office. you will need to swear an affidavit, and they can help you. mine is the same length as yours, 24 feet tongue to bumper. mine was avocado appliances, originally, replaced with correct vintage yellow ones, including an original fridge (woohoo, it still works) from a travelux being gutted for a bunkie.
brakes are kelsey hayes, your stove a midland enterprises made by greg lund products? duotherm furnace, allanson charger/inverter?
i have some electronic copies of manuals, that i am willing to share, as such info can be extremely difficult to find
some photos follow of my unit. note the window placement on mine is similar to yours. you may have a unit that is very early. travelux were built, as i understand,
1966 to 1978. trademark was registered 1966-02-03
you have a treasure, please don't "update" it, enjoy the vintage aspect. my wife and i use ours for the barrie spring auto flea market every year, very comfortable.
