Oh yeah, they've definitely lightened them quite a bit. Ours is a 2012 Flagstaff 32' with double slides, and it is 7900lb unloaded. I haven't weighed it, but I'm guessing it's around 9000 or so loaded without water. I normally don't tow with the waste tanks full, but honestly, I can't tell a difference when they are.

 

The fresh water tank is over the axles with one grey tank behind the axles and the black tank with an additional grey tank ahead of the axles so with all four full if I'm remembering the tank capacities right I can have about 130 gallons on board. Like I said it's very rare that I have all four are full at once but it has happened and 8.3# per gallon that's quite a bit of weight to be adding.

8.3#/gal*130/gal= 1079#

 

The 6228 truck weight is with the hitch, I did one weigh with just the truck on the scales and then hooked up and weighed the entire rig.

 

Sounds like you've got your bases covered!

 

Here is a better shot of the truck hitched up.

 

Must have the neighbor with the GM in awe.

 

With the trailer hitched up, did you get the weight of the truck? THAT is going to tell you where you stand - compare that to GVWR.

 

6228 truck weight, 7700 GVWR 7950 actual axle ratings

 

Just got back from our first trip with the fiver, avg'd 9.0mpg for the trip. Was getting mid 9's going up there, but hit some head/cross winds coming home so it dropped the average down to 9mpg 340 miles, 37.5 gallons used. Truck pulled fantastic, very stable even in windy conditions.

 

The MPG is what it is towing = not good. Hell, i'd be very happy w/ 9mpg that load. The most important part is safety, which sounds like it was stable and you never felt overwhelmed. That's huge!

 

I don't think he's complaining about the 9 MPG, just sharing what it was. I barely get above that without towing anything haha

 

Definitely not complaining, as much weight as I was pulling it did very well.

 

awesome, that mileage would probaly be pretty comparable with todays stock diesels

 

Not even close. His numbers are about 1-2 MPG less than my fuel-hog 6.4L. The new 6.7L PowerStroke will pull about 12-13 with that load. My dad had a 2011 6.7L (he sold his fiver and truck), and towing a 32', 8k (unloaded weight) fiver, he would regularly get between 12 and 13 depending on speed. These are hand-calced numbers. We had nearly identical fifth wheels, and his '11 6.7L would get right at 20% better fuel economy than mine.

Empty, he would get about 25% better than mine. The new 6.7L is a marvelous piece of machinery.

 

6.7l diesel is around 10 grand more than what I paid for my truck, as well you have to buy Diesel exhaust fluid and then on top of that diesel is 3.99 where as gas is 3.49 here.

It would take ALOT of towing miles to break even in a diesel.
