On paper, the nine-year-old Adventurer 86SBS model and the ten-month-old Adventurer 89RBS have a lot in common. Both are essentially nine-foot (8’9” for the 89RBS versus 8’6” for the 86SBS), full-wall-slide, wet bath truck campers that utilize Adventurer’s True Composite Construction (TCC) and the latest Adventurer model year updates.
With three extra floor length inches, the base dry weight of 89RBS (3,018 pounds) comes in at just 41 pounds more than the 86SBS (2,977 pounds). Since the fresh, grey, and black tank capacity (38 fresh, 31 grey, 31 black), propane tank capacity (two 20-pound vertical tanks), and battery capacity (two Group 27s) are identical between the two models, the calculated wet weights are just 41 pounds apart.
The only other two specifications that are different between the 89RBS and 86SBS are the overall length (16’8” for the 89RBS versus 15’10” for the 86SBS) and center of gravity (38-inches for the 89RBS and 37-inches for the 86SBS). Even the base MSRPs are close; $29,540 for the 89RBS and $28,497 for the 86SBS – a difference of just $1,043 (or 3.66-percent).
If you were looking for a clear choice in the specifications and capacities, you’re out of luck. Even the full-wall slides are both on the same driver’s side. So what are the big differences between these two models? Three things.
First, the dinette in the 86SBS is a U-shape versus a full-booth Dream Dinette in the 89RBS. We greatly prefer a full-booth Dream Dinette for its table stability, ease of bed conversion, and overall big table functionality. Unless you need to seat five, the Dream Dinette is a winner.
Second, the wet bath in the 89RBS is much bigger and located in the rear passenger’s corner versus the smaller wet bath in the 86SBS that’s located mid-ship. We love having the separation a mid-bath creates between the cabover and main living area, but some folks prefer the more wide-open floor plan that a rear bath offers. Because the bath location will boil down to a personal preference we’ll call this a draw, but we sure prefer the bigger size and improved design of the newer 89RBS wet bath.
Third, while both campers fit long or short bed trucks, only the 89RBS allows a generator for the short bed option. This along with the myriad of design refinements Adventurer has worked into the 2017 Adventurer 89RBS (night stands in the cabover, entertainment cabinet, additional rear window, etc.) and it’s tough not to declare the 89RBS the winner.
In fact, we’re going to call this – at least for us. If we were choosing between these two units, it would be the 89RBS, hands down.
Floor Plan Evaluation
As an experienced truck camper, I find myself attracted to design choices that make day-to-day truck camping life more simple and more intuitive.
This explains why I was pleased to open the entry door and find the Happijac jack remote in a dedicated pouch on the driver’s side.
The slide-out controls, power awning control, and light switch are on the passenger’s side.
The very next thing I noticed was what looks like a compartment, only it has a sticker that reads, “THIS IS NOT A STORAGE COMPARTMENT”. Although I did not open this not-a-storage-compartment, it likely gives access to plumbing under the wet bath – a welcome feature for maintenance.
On the rear passenger’s side is the big wet bath. Look at the floor space in this one-piece, molded fiberglass, wet bath beauty! No shortage of toilet leg room! No lack of shower elbow space!
