It usually the payload number that really limits you with the Expy. 9200 tow rating is very nice, but if your payload capacity isn't up to ***** then it really affects how the set up rides.
Jason's sticker says 1460lb max payload, but my Expy is only 1402lb, I imagine because it's Eddie Bauer version, perhaps more options, usually means less payload.
In my case....
1485lbs : over by 83lb
- Hitch weight of trailer, 700
- battery, 45
- propane tanks full, 30
- Stuff in front storage compartment of RV (grill, chairs, tools, hoses, etc) conservative 50
- Equalizer hitch set up, 100
- Cooler in back of Expy, 40
- Large Rotty dog, 120
- My fat azz, 280
- Wife, 120
Now, a true metric would be going to scale and have it really tested, but this is just a rough estimate. So, I'm often over my payload capacity on trips. It stinks, just the two of us and the dog and we're over. Can't even invite anyone for fear of really pushing the limit. Lately I've been moving stuff around to reduce the weight on the hitch. Nix the cooler, move items out of front storage to back over the axles in the RV, only filling one of the two propane tanks when really needed, running lean. Need to get on a diet too, that would definitely help, easier said than done.
My point is, tow capacity is really just one factor in the over-all set up and for an Expy the payload capacity is the true limiting factor.
I’m wondering why you add the battery and propane weight to hitch weight. I would think the battery(s) is always on the trailer and you might as well always assume full propane. Same goes for gear in the forward cargo compartment of trailer. The hitch weight is the hitch weight regardless of how you arrived at it.
As an aside my 2017 Limited 4x4 shows occupant and cargo(payload) is 1356#. Taking the GVWR of 7500# and full fuel of 28 gallons for 168# this calculates out to an empty weight of 5976#. It’s difficult to come up with the advertised empty weight. The specs I’ve found online give a curb weight of 5562# but don’t distinguish for trim lines, accessories or options such as 4x4. But the 5976# number calculates to an additional weight of my Expy of 414# versus a bare bones one. Even worse it’s 582# heavier if curb weight includes full fuel. This is almost as bad as general aviation airplanes where the actual weight is usually far greater than the advertised weight.
All that said, if you take my car empty, add my 200# and full fuel I am at a max towing capacity of 8856#, definitely less than the max towing capacity of 9200#. Much less if you through some cargo in the Expy. So, from a practical standpoint, it’s unlikely any of us can tow the advertised 9200#.
