Alaskan 650 SI truck camper
The Alaskan 650 SI is an Alaskan slide-in camper model. The figures below are the maker’s own, as printed for the 2026 model year, each under the label the maker uses. Nothing here is estimated or carried across from another year or model; a figure the maker does not print reads Not published.
In short: floor length 77 7/8”, overall length 134 7/8” (2026, as printed). A truck camper rides in the truck bed, so what matters is its loaded weight against the truck’s own payload rating on the door-jamb sticker. Water, propane, batteries, gear and options all add to the printed weight.
