Springs going on now. Woot!

*Citation needed First off, I never told you my target completed weight. I could be 30% under the tire rating for all you know. Secondly, you now appear to be claiming that a tires rated load is now "overweight". There are in fact de-rate factors when using tires in certain applications...

So you don't have a source, and those are your personal targets. It is totally fine to have personal design goals, but please don't go around telling folks to derate their tires 18% without that caveat. If you got that data from an AI summary, I strongly advise to find some better first...

But where did you source those tables from? (I sincerely hope it wasn't from an AI summary). I am not arguing against safety margins, but 18% is a very specific and fairly high margin. The wheel and tire manufacturers load tables for commercial and LT tires already have some safety margin...

There are several posts above, including one with a weight distribution spreadsheet. So yes, I am paying attention to axle weights. What is the source for the specific 82% value (18% de-rate)? 12ply is a leftover from the equivalent ply ratings for bias-play tires, it isn't very useful...

Won't know until the vehicle is fully loaded, but the cross member is about 4.5" below the bottom of the frame rail, give or take, and the Tcase is about level with that. So some impact to breakover angle. The Tcase is fairly close to the front axle, which mitigates the breakover impact some...

Transfer case going in. I am enjoying a fresh/new chassis for as long as I can. Knowing me it won't ever be this clean and rock chip free again!

Cool! Yeah, I considered DIYing the 4x4 bits, but my back and elbow aren't what they used to be. To clarify the chassis is getting its running gear installed. We are tentatively in the 1st quarter 2026 queue for getting a box installed.

Vehicle going under the knife.

Yeah there's a few different considerations. I'll probably have a 50 amp hour LFP standby battery on my 12 volt bus. A dedicated 48 to 12 for the 12 volt bus. Adding a current limited direct connection between the starter battery and the house 12 volt bus could be used for trickle charging...

That literally has nothing to do with the setup I am discussing, and even then there are a bunch of assumptions that only apply to what appear to be your usage case. The hubris is quite stark actually. I am discussing a second alternator with a 5 kilowatt output. And using a $80 DC/DC charger...

Huh, what are you talking about?

I don't have a ton of 12 volt chassis loads, so the stock to 250A single alternator will work fine. With a dedicated second alternator charging the house battery I think that's the way to go. I think I'll install a 48v-12v dcdc to keep the chassis battery topped up.

Huh? There are extensive conversations about it. Asking an expert is a good option, if you are just googling for adverts, yeah most companies are just posting details on what they sell. Same goes for influencers on Youtube etc. Again, if you want to make blanket claims like that, I suggest...

I ended up buying a custom ordered (order abandoned by initial buyer) 2024 E350 SRW cutaway for a good price. I am having Ujoint put a basic 4x4 conversion on it. With careful attention to weight it should meet my needs fairly well. Fuel economy isn't great, but no diesel emissions gear to...
