Is that the Eagle 355MBQS? That is a really nice looking rig, they had one might have been a 2022 next to the 312BHOK the wife and I were looking at. Salesman was trying to sell me on it... way too much for my F250.

 

We like it. I had a 17 250 and sold it so we could get that trailer.

 

I always buy new tires for a new truck. factory tires are junk.

 

GD lists the GVWR for a 310GK (current year) at 15K, hitch at 2350 but that's dry. Even then that only leaves 250lbs for you and your wife and whatever snacks etc you want with you in the truck.

I would consider moving up to a 350/450 with more like 4k+ payload and then you can look at useful mods like auxiliary fuel tanks and onboard air compressors.

 

This can be said for almost any new vehicle...I usually tough them out until I get disappointed, then replace them, lol
That being said, the wranglers are not that bad. We'll see how long they last this time.

 

Here's the skinny on tires and weight ratings. GAWR are listed at the weight the tires can support. An All Season has a lower weight rating than an All Terrain. So when it leaves the factory with an AT it will have a higher GAWR which then translates into a higher GVWR. If it has AS tires, the GAWR and GVWR will reflect that, and the tires and capacity sticker will show the tires it was rated at. Swapping AS for AT will give you that extra capacity, just not on paper, the CCC sticker and GVWR are still set in stone on the truck.

Tires are the weakest link on the suspension.

 

....but they aren't. My truck tire load ratings on the rear are 11,640 lbs and my GAWR is 9,995 lbs....Our F350 SRW has a GAWR of 6,780 lbs and the tires are rated at 8,160 lbs. I've never seen a truck that has the GAWR exactly equal to the tire max load rating which implies that it isn't the tires that dictate the GAWR?

The rear tires on my truck are rated at 15,000 pounds and the GAWR is 9900. GAWRF is 6000, tires are 7940, GAWR combined is 15,900, tires combined is 22,940, yet the GVWR is 14,000.

Also GVWR is less than both GAWR combined. It's percentage based. What those percentages are, that is up to the engineers. The tires do make a difference between AT and AS GVWR though. It comes down to if one is D rated and the other is E rated.

However, if you look at all the tire choices, they are all E rated tires now, the only real differences are the 33" tires, which may have a lower weight rating as they are not E rated, and that can affect GVWR.

 

Has anyone come up with a GVWR calculator sheet that could help guesstimate our rigs?

 

That would be very helpful.

 

2 vehicles most likely will not be the same so you must figure it yourself with your own belongings and vehicle weight from a scale.

It doesn't get much easier than this posted in the Ford rv and trailer towing guide.

 

On a 5th wheel, take the dry pin weight and add the full FWT weight to it as a starter. Add about 1500 pounds to the GVW for "stuff" because on average, that is what will be added between gear, food, clothes, bedding, towels etc. Stand to the side and look at the trailer and picture where you would be putting things in it, what it might weigh and picture where the weight will go. This is the closest way to estimate your trailers weight. Always confirm it with a CAT weigh. When I shopped for a 5th wheel I looked at ones that had the lighter % dry weight because the weight will only go UP. You want to avoid a 5th wheel that has a 20% or higher dry weight that is NOT a toy hauler because that pin weight will only be heavier.

My 3660SUITE had a 17% dry pin weight, and I maxed the weight out, 60 pounds under gross with a full FWT and the pin weight is at 21%. The front storage passthroughs have a lot of stuff in them.

 

I was told speed limits are not valid numbers, and bridge clearance numbers are fake..........

 

I have to remind my wife that posted speed limits are just suggestions. Never goes over well.

 

The FWT (full water tanks) has been accounted for into the GVWR...as stated on their GVWR decals, states full clean water tanks...the gray and black are NOT included into this equation.
