I'd like to see how they are made. I thought it would be a structural sandwich, but I guess not. 1/4" is thick... a sandwich panel would be more like 1/8" on a side with nothing but foam in the middle.The 1" aluminum tubing frame should be pretty light and I think the outer fiberglass body is only 1/4" thick or so.
Yes, pickup frames are all boxed and very stiff in torsion now... C&C are still C channel behind the cab.I think I've read on here once or twice that modern PUs don't require a sub frame so that's might mean less load to build.
You hit the upper limit on payload REALLY FAST with the 350/3500 SRWs. You need to go DRW and single them out.Pretty sure you could fit 37s under either pretty easily. The 1 ton (350 3500) C&C can be had with SRW, so I guess that is what TruckHouse did. I think it would have made sense for TH to go with a 4500/450 (which are only dually) and SS for the much better turning and wider track... but maybe the suspension options are lacking, or AEV doesn't do those?
Rossmonster may be using the pickup chassis (which are boxed and stiff and don't need pivoting subframes) on the Baja, but each chassis manufacturer will have different bed mounting points, compared to the C&C which all have standard width C channel rails.
It would be interesting to test what real gains in load capacity can be gotten when going from a SRW 350/3500 to a DRW 350/3500 or 450(0)/550(0) with an aftermarket SRW conversion. Without doing an axle replacement, I don't know if the as-engineered DRW GAWR holds when replaced with a custom SRW setup...any engineers out there? In any event, if you have a camper on a pickup/chassis truck, be it a 4Wheel slide-in (quite light) or an Earthroamer (not light), I would really check carefully to ensure you have GAWRs that can easily handle what you're going to be carrying.You hit the upper limit on payload REALLY FAST with the 350/3500 SRWs.

Ford publishes the numbers online. There’s an upper limit difference of around 1,000lbs (if my memory is correct). Given how low the payload is to start, it’s substantial.It would be interesting to test what real gains in load capacity can be gotten when going from a SRW 350/3500 to a DRW 350/3500 or 450(0)/550(0) with an aftermarket SRW conversion.

I don't know if Ford (and Ram) provide a different axle for SRW in 450/550 or just use some kind of an OEM spacer/extension?Ford publishes the numbers online. There’s an upper limit difference of around 1,000lbs (if my memory is correct). Given how low the payload is to start, it’s substantial.
Are we talking about converting a DRW to super singles or just buying an SRW? I was referring to the latter.I don't know if Ford (and Ram) provide a different axle for SRW in 450/550 or just use some kind of an OEM spacer/extension?
At least some expedition campers have in the past taken factory DRW F550 axle and then extended it (e.g. Dana S110 and 130? on Earthroamers) to result in a camper-width SRW setup. IME, there shouldn't be any drama with GAWR, if you're well under limit when fully loaded--- mine's been perfect for 14+ years of roaming around, provided you know your GAWRs, maintain your axles/wheel bearings/etc. correctly and can always stay on top of how much you're carrying.
When you wrote "You need to go DRW and single them out" above, I figured you meant turning a DRW into SRW.Are we talking about converting a DRW to super singles or just buying an SRW? I was referring to the latter.
Well, turns out I'm a flippin' idiot!When you wrote "You need to go DRW and single them out" above, I figured you meant turning a DRW into SRW.
I had nothing to do with these posts!Well, turns out I'm a flippin' idiot!
