Understood.
Thus sayeth my dealer, who performs warranty repairs for me:
Thou shalt not put larger diameter tires upon thine vehicle under penalty of voiding thy powertrain warranty.
I can go wider, but not taller. The reasoning is that the increased strain could be used to explain the added wear and tear, so until I hit 100k I'm staying at 32" tires, which are already decent sized. Not as big as I'd like, but big enough for now, and there are a great many other mods I have to make that don't affect the drivetrain, not even a little bit.
If I go wider and I am, then I still have to replace the rims to get the proper backspacing. Since I only want to replace them once the earlier convo still applies, but I am seriously, very seriously, looking at 17's for summer and 18's for winter to compare them. If I do this then I will have worn out 3 sets of tires total about the time the drivetrain warranty kicks it and I can do my lift then.
So 4 years out on the lift. Given how much has to get done and how much money it will cost I'm alright with this.
Looming close is the trek I take every Leap Year. The cargo issues I have as a BOV
must be fixed or at least stop-gapped by June.
Here goes nothing.
To get the cooler out of the cab and into the cargo area, I'm getting a pair of these:

1 tube up front, one in back, and we are good to go on soft drinks while driving.
Cargo? I got your cargo:

Only getting one of these. I'm leaving the other side open for a fire extinguisher at a later date.
That is not nearly good enough though, so:

These fit over the wheel well on either side of the back seat, leaving the seat open and the view there for the rear passengers.
And I still need a cargo rack on top of this. For the trip I'm going with a receiver basket as a temporary solution. the bikes and canoe are not making the trip so compatability is a non-issue. I'll be finding a use for it later on down the road, possibly as a welding project over the winter.
Other things on this timeline include the rear license plate braket needs replacing and a ding pulled from where something hit it. Finally, I'm converting the front bumper to a stubby to get rid of a beauty mark from when I went off-roading last year. Minnesota requires the bumper extend 10" beyond the frame rails and this bumper is (just) legal there.
Deadline on all of this is May 22 for ordering parts.
