Here's my work truck. When it comes to hauling loads longer is better and so are DRW. I don't know how anyone could argue that.

An extended cab, a 4-dr and a dually would handle my camper better than my regular cab SRW does. Probably a lot better, especially a dually.

Regular cab. The best looking trucks.

I have had the same camper on a regular cab and an extended cab. Both trucks long bed F-250 with camper package. Extended cab was better on highway (wind, semi trailers) but the off road and turning radius better on regular cab.

On a straight truck that would that would only happen if the cog of the load is in front of the rear axle . Usually minimal if at all with a TC .

The longer wheelbase makes it possible to move the COG forward.
Pickup bed is normally centered over the rear axle. To load a pickup to GVWR the product must be pretty dense. And even if the load is centered over the drive, moving the steering forward will make weight on front remain more constant as the rear hits road bumps, so handle better.
When I posted it was a reply to somebody saying shorter would put more weight on front.

TCs don’t have movable COGs. You get what the factory builds. The pickup bed is never centered above the rear axle on purpose by factory but can happen on really short bed trucks. Most pickups with TCs are near or over GVWR.

I’m not sure what you mean when you say even if the load is centered over the drive.

I think you are confusing that long big trucks are built to have higher GVWR when they make them longer with pickups that don’t. You can go look at the GVWR charts for any pickups to see this fact. Likewise, the most payload for trucks can always be found with the regular cabs compared to crew cabs. Again, you simply need to look at the charts.

Pickups typically have exactly the same rear axle/front axle/transmission no matter which cab they have. They don’t change the brakes etc just because you have a longer cab.

Longer wheel base isn’t mutually exclusive to higher gvw. Talking big trucks here.
It’s actually not much of a factor for the truck itself. However it can be licensed higher based on highway and bridge laws.

Yes, the COG is not moveable, given the limited places to put weight, and the limited amount of weight that can be added. OTOH, when shopping for camper/truck, you should be aware of where that COG will ride in the bed.

If you compare length ratio front of bed-axle/axle-back of bed on a pickup bed to most truck beds, it is centered.

If the COG of a load is over the rear axle of the of the pickup, increasing the weight of the load will not change the weight of front axle. A shorter wheelbase, having a smaller percentage the GW on the front will affect handling more than the same changes on a longer wheelbase. Of course, if you must have a pickup, to get the long wheelbase you also get the extra heavy cab.
