Great article on the 840 Mike!
I've been tossing around the idea of adding a truck camper to my fleet and the 850 is #1 on my list since I want to keep my short bed F250 around and I know any of the heavier slide models just don't make sense on this truck.
I decided to stop by Apache Camping Center in Portland Wednesday afternoon on my way home from a week long trip to Bend to take a look at the 850 and I was surprised to see one of the 840's on the lot. It didn't even hit me what I was in until after I got out of it and into an 850! ;)
I now realize I have a bit of thinking to do between these two models, as the 840 feels much roomier in the kitchen/dining area, as there is no squeezing between the table and bathroom to get in and out of the camper like in the 850. I initially wrote off the 840 because of the cave-like effect in the cabover with the mid-bath and what I believe to be a lack of TV mounting options that allow one TV to be used in both the cabover and the dinette, but now I'm thinking those may be fair trade offs to get a little more elbow room in the main living area.
I was very impressed with the build quality of the Wolf Creeks and am glad to see manufacturers realizing there are people out there that are looking for quality, but don't want or can't carry a multi-slide behemoth or pay the price for a Northern Light or Bigfoot full fiberglass model.
I'm still in the daydreaming phase of a truck camper purchase, as I still really like my trailer, and it would be very difficult to justify the expense of a new camping rig, but I love the flexibility I would have with a truck camper. There's just so many places I would like to go that I know my trailer either wouldn't survive the trip or fit once I got there.
