Hi Jack
Sorry for the delay in measuring the Gipsy heater. The main casing is 340mm long, 200mm wide and 50mm deep. The motor protrudes about 80mm from the casing and there are brackets on the back 35mm deep which give a clearance for the air intake. Some heaters have a single speed motor which is slimmer. I dismantled several Gipsys many years ago and am currently building a flexitor Gipsy with a Land Rover body.
Cheers Richard
