I am in the same situation … just started researching the truck pop-up camper options. Pretty sure this is the direction we want to go. Don’t own a truck currently, so the big decision for me right now is do I need to buy a 3/4 ton pickup or can I get away with a 1/2 ton. Diesel or regular fuel? Any knowledge out there on gas mileage differences b/t 3/4 tons and 1/2 tons? We would like to get a pop-up with cassette toilet and indoor shower (which most likely puts us in the 3/4 ton PU market).
