Having owned two English Sprite "Caravans", a 1967 and 1972 I can tell you they are much lighter then what we have here.
There was a bulb on the floor with a hose under the trailer you put into a water container.
The first was a 1967 13', no battery
tank, 2 burner stove and a GAS LIGHT
, bought that one new! The second, a 15' was bought used and had a closet where a porta potty could be put.
Compared to the Scotties and the rest of the trailers of that vintage they were feather weights.
There were not even tanks for water, gray and black either.
Both had surge brakes
with a hitch that would allow the TV or trailer to "roll over" with the other remaining on the ground correctly.
