welcome and hope you are having a great holiday.
Quite a few people ask about converting full size pickups and 4x4's to EV. As with any vehicle, conversion is possible, but weight and efficiency of the chassis is going to be a major factor in the cost and performance (especially range) of the end result.
A fairly easy back-of-envelope / rule of thumb for range is to look at the original gas mileage of the vehicle - for that truck 12-14mpg is probably the best that could be expected (I had a 77 ramcharger, similar sort of thing, it got 11mpg with an automatic and 14mpg when I converted it to a manual)
With a lithium battery pack, you can figure for every 5% of the overall weight of the vehicle as batteries, you will get about the equivalent range to what it would have gotten on 1 gallon of gas. There will be some variation from the type of lithium you use (telsa, leaf, volt, LiFePO4, etc)
So for example if the truck weighs 5000lbs as it sits, and after conversion you have a 1100lbs battery in a 5500lbs vehicle (20% ratio), you can probably expect about the equivalent of 4 gallons ICE range or maybe up to 60 miles.
Applying that calculation to my scion xB (600lbs lithium in 3000lbs vehicle) The original ICE EPA mileage was 30, in which case I would see 120 mile range as an EV. Actual driving mileage was probably more like 25mpg overall, and the car has about a 100 mile driving range under good conditions.
Here's the best comparable pickup example, built by an EV club member in seattle:
