2013 Adventurer 89RB

The floor plan is significantly more open in the 89RB.  By putting the wet bath and dinette in the rear, we really opened up the camper.  To further increase this sense of space, we went to much larger 20” x 62” side windows as well.

TCM: Since the 89RB was based on the success of the 86FB, why are the tank sizes different between the 89RB and the 86FB?

Greg: When we designed the 86FB, we used existing holding tanks from other models.  We started with a blank slate with the 89RB, including the holding tanks.

In the 89RB, the propane tanks, batteries, furnace, and hot water heater are located as far forward as possible.  As a result, the center of gravity on the 89RB has come in at 36.5” making it easily fit into the short bed trucks of today.

TCM: That’s excellent, but why are the 89RB grey and black tanks smaller than the grey and black tanks in the 86FB?

Greg: The 89RB holding tanks are 42 gallons fresh, 25 gallons grey, and 22 gallons black.  These tanks sizes give the 89RB the proper blend of transfer to the grey and black tanks.  We want the combined capacity of the grey and black holding tanks to be a little more than the total capacity of the fresh tank.  For the 89RB, the grey and black holding tanks offer five more gallons than the 42 gallon fresh tank.

We were able to properly size the tanks in the 89RB and design a camper with more storage and a much better center of gravity.  More importantly, using the proper size tanks removes weight and cost from the camper.

Above (click to enlarge photos): Center of gravity is measured on every camper at the end of the production line. Then a COG sticker is placed on the camper.

TCM: Speaking of center of gravity, how does Adventurer calculate center of gravity?

Greg: When an Adventurer or Eagle Cap truck camper is completed on our production lines, it is weighed on a calibrated scale before leaving the building.  That weight is then posted inside a cabinet in the truck camper.  That’s your dry weight with options.  Of course any options added by your dealer after the camper leaves Adventurer add weight to the camper.

When we weigh each camper, we also put a fulcrum on the scale to find the exact center of gravity for that camper, including factory installed options.  We then mark that center of gravity on the camper exterior with a red arrow.

TCM: Do you often see the same model truck camper, with different options, having different center of gravity points?

Greg: Yes, we have seen the center of gravity move from camper to camper based on the options that were added to the camper.

At an RV show last year I noticed that two of the same model Adventurer truck campers had stickers for center of gravity in different places.  I came back to the factory and said that the stickers must be wrong.  That’s when I found out that we measure center of gravity for every camper we build.

A few months ago, we tested a camper with full fresh water to see what happened to the center of gravity.  The fresh tank was located all the way forward and the center of gravity actually moved forward four inches with the full tank.  With the way we designed the 89RB, I have no doubt the center of gravity would move forward with a full fresh tank.
