No rain at all! If anyone ever has reminders please share them. I did consider the pinion angle although I never mentioned it.

When I decided on swapping out the axle I found the thread by Griggs on his 14 bolt swap and used it to get started. He made clear the importance of driveline angle so I factored it in during the mounting. I measured the pinion angle of the HO52 that was in the truck and it was 2*. So from that I figured 2* would be a good place to pin my angle for my 14 bolt. Once in the truck, unloaded, the pinion measured 0* and the transmission out put shaft measured .6* down. The specs at the link you sent me, thank you for that, don't show a unloaded vs loaded weight for a cab and chassis but for the regular pickup truck it gave a difference of 4 inches. I just realized I misread it and thought it said two inches, and thinking there was 2 inches difference between loaded and unloaded I used my front end loader to compress the rear two inches and remeasured. I got .6* on the pinion and 1.2* down on the output shaft. So we maintained the .6 angle differential, which from what I've read is acceptable.

A couple things to note, I do not have level ground. There is no concrete for me to use that doesn't require dragging the truck somewhere. The front end loader is all I have to "load" the truck as there is no bed for this truck. I'll have to build it. To me what's most important is that the driveline maintained the same differential from unloaded to half loaded I can only assume it will do the same at max load. In the worst case scenario I can shim to increase the pinion angle if absolutely necessary.
