eddiel,
On 8/1/2013 I weighed my BF at an Alberta Province official weigh station in Slave Lake, AB, Canada.
I had a full gas tank, 3/4 fresh water tank, 1/4 full holding tanks (I always use water from my fresh water tank, not from the city water supply so the total has to either be a full fresh water or full holding tanks) and full propane tank.
Front axle max allowable. 4600lbs
Front axle actual 1670 kg or 3674 lbs. ( One kg equals 2.2 lbs )
Under max allowable. 926 lbs
______________________________
Rear axle max allowable. 9450 lbs
Rear axle actual 4370 kg or 9614 lbs
Over max allowable. 164 lbs
My dog and I were onboard. 170 lbs for me and 50 lbs for my almost human dog. I was traveling full time then. More stuff than the vacationer. A big tool box, a socket set, an electric drill, a bunch of nuts, bolts and the like. An almost full refrigerator as I was about to encounter some remote Canadian areas, and lots of craft beer as I was afraid I would exhaust my supply. And I had a spare tire mounted on the rear that weighs 70 lbs including the rim but not the mount.
The next time I had a weight check was on 9/9/2013 at Tok, Alaska.
Front axle 3760 lbs. Under max load -- 840 lbs
Rear axle 9700 lbs. Over max load --- 250 lbs
Full gas tank, full water tank, empty holding tanks and 1/4 to 1/2 full propane tank. Every thing else same as 8/1/2013 load.
If you carefully analyze these results they are slightly in conflict. The first instance totals 13,288 lbs and the second 13,460 yet the second weighing was with less propane. Maybe the dog and I gained 172 lbs in that month.
On a BF motorhome it is common for the front axle to be significantly under the max allowable weight. There is no practical way to transfer significant weight from the rear to the front axle.
I encourage others reading this post to provide their facts and opinions.
