It would be interesting to see where that extra weight is coming from - as much as 440 pounds if we take the differential people weight into consideration, take it off the total difference. That's a lot.

EDIT: Back when I was evaluating this issue closely, I dropped every single item onto a bathroom scale before loading it into the van. Obviously (1) I have gained a few items since I did this and (2) this does not include the weight of stuff that "lives" in the van year-round. I might repeat the exercise again this summer if time allows.

Anyway, this is why I say that a 440 pound differential between vehicles seems to be significant, at least to me, because I don't even take that much cargo in total.

WHOA! Thank you Boxster1971! I was NOT aware that MB now had a 4500 Sprinter in their line up. In 2013, I fell in love with a 25' Flying Cloud but, the 3500 Sprinter I then owned would have easily gone overweight. The dealer did me a favor telling me that HE would NOT sell me a 25'FC. He offered a 23" which did not interest me. I've since gone to a Freightliner based Super-C diesel puller motorhome. As long as I don't start an anvil collection, I'll never be overweigh!

The correct maximum roof loading is 660 pounds for a low-roof Sprinter (any length) and a mere 330 pounds for a high-roof Sprinter (any length) for equally-distributed loads. Thank you for asking about the source since it forced me to verify and find my mistake.

ROWIEBOWIE - The E&P Leveling system adds 150 lbs. I had 39% more fresh water (10.14 gal = 84.56 lbs.) and 5% more grey (1.35 gal = 11.25 lbs.). So that accounts for approx. 245 lbs. And adding his crew weight of 400 lbs.. (from his figures), so I am still 195 lbs. above WACHUKO's weigh-in.

I do have the 4 yr. old and a 8 mo. old unborn baby in pregnant daughter's tummy. Also, the Lounge has 14 automated shades/motors vs. half that on TB. But all these won't get to 195 lbs.

I think WACHUKO just has skinnier & slimmer crew than me, even though we are shorter. I think crew and I are the ones needing to go on diet

Page 216 in the 2006 manual - same values were given. I've learned something new today.

From your list of hauling stuff I think you are good.
Getting a Class A does not guarantee you won't be overweight. A close friend, who is an engineer on the US Army MRAP program, bought a Class A. Then he started looking at the axle component specs after he had his rig weighed. The RV manufacturer had installed the wrong axle for the version he bought. The rear axle was overloaded by nearly 1,000 lbs. The RV company replaced the axle after he pointed out their error.

https://en.wikipedia.org/wiki/MRAP

The problem with RVs is that they run fully loaded almost all the time. Even an 80,000 lb. concrete truck is driven under its limit once it dumps its load.

But I agree being only 90 lbs. over the GVMR is not a big issue, and well within the design margin.

Alex,

Another data point on AI weights.

We had our 2014 AI weighed by Escapees (they weigh each wheel position). Total weight of our rig with 2 people, our gear, and full fresh water tank (black and grey empty) was 10,200 lbs.

We were far enough below GVWR that we immediately reduced tire pressure all around (after consulting the manufacturerís table of weight vs pressure).

We donít have VB air or hydraulic levelers, and donít carry more than 2 people. Our AI is the non-extended (23 foot) version.

Bottom line...the only way to know for sure is to weigh it!

We put our solar panels on ours, so we had to evaluate that.
Protagonist was quoting the limit close for a low roof Sprinter, which is 660 lbs.

But the high roof Sprinters, be they T1N or NCV3 have always been 330 lbs.

Attached pages from a 2006 and 2015 Sprinter owners manual. High roof vans have a nasty habit of rolling over, thus lower roof load limit.

Enjoy,

I've had my 2013 weighed twice.

In 2014 at scales used by my dealer; driver only, full fuel, full fresh water, but propane empty = 9,980 lbs.

In 2018 by RVSEF at FMCA Rally in 2018 after upgrading batteries and Inverter. Two people, full fuel, full water and full propane = 10,875 lbs.

Forgot to post this - I only have 1,397 lbs. to play with. I would imagine a 2019 with 4x4 , VB, E&P, sat dish, 4x batts, extra Tommy Bahama gear would have even less than 1,397 lbs.
