Phil, The 2022 Ram Bighorn 1500 4 x 4 has these dimensions: Length of the bedrails: 80" Width between the bedrails: 62 1/2" tailgate and cab Bedrail width at the cab: 5" Bedrail width at the tailgate: 3 1/2" Height from the bedrail over the cab and antenna: 25" Height from the bedrail over the cab without antenna: 22" Thank you for any suggestions you may have.

Hi Phil, Thank you for your reply. I’ll keep the sleeping platform attached so I can use the interior stand up aspect of the truck bed. I’m concerned with the ability to insulate the camper. 1 or 2” foam board attaches easily to the wooden frame. I’ve not seen much insulation in the aluminum builds. Will you have plans or kits for the 2022 Ram 1500’s? Or would I need to adjust your plans to the Ram’s dimensions?
