GURPS Spaceships, upscaling sizes

Sorry (not sorry; never apologize for Spaceballs)... But that's about the right size, given most RVs can run SM +4 (the really small ones with a single bed over the driver compartment) to +6 (larger bus-sized Class B/E* (depending on locale) types). If using "Alternate Spaceships" from Pyramid #3/34: Alternate GURPS, the bulk of the Middle and Rear sections are probably a Habitat regardless of what Spaceships says, but said Habitat would take up something like 10-12 modules, using the rules for oversized modules (I think they're in SS4 or SS7).




* In South Carolina where I am, the Class B and Class E cover the same weight class, more than 26,000 pounds/13 tons gross weight, equivalent to a bus, large RV, or large cargo truck without a trailer; the B is the CDL license, while E covers non-commercial stuff of the same weight class. A and F are for the semi-trailer types, commercial and non-commercial respectively. Some states require a Class B license (CDL certification optional) for the larger bus-sized RVs.
