For two people I think a well equipped over the cab truck camper is ideal . It gives you all the creature comforts needed while still being able to " rough it " to areas a pull type trailer can't access . Obviously parking is much easier as you are basically at the same length as the truck but taller . I agree that buying used is much better than new , the depreciation is horrible on a new one .
Or you can go old school like I did . While I haven't done anything to mine since I gutted it she's in queue for restoration . I have a soft spot for these old Avions . When looking at a used camper regardless of truck camper/travel trailer/motorhome you want to inspect for leaks ........... then leaks ............ and finally leaks
. All of these rigs are prone to roof/sidewall leaks so a good inspection is needed . Just like cars for sale that state " ran when parked " the equivalent in the RV world is " roof leaked but been fixed " .
Here is the thread I started on mine . I hope to get back to her next year .
