Hmm, now that update is in? Uh...NO, not a good deal for you.
A while back had a 400 swapped in (different vehicle), ended in $4k of bad dreams.
After that fiasco, thought I had learned something...nope, still learning.
Had a college try to do a rebuild on my 84 305 at 200k (g/f's father was main tech/teacher), they screwed the pooch on that after 6+ months of waiting, they showed me a bright orange (oops, clue) painted rebuild on the shelf with "we can put this one in now" since g/f father died due to a car falling on him doing a "just be a minute" quick thing without the jacks stands...still learning.
Three times the cost later, engine turned out to be a messed up 77 2bl Caprice engine, a Big no no for CA smog, college said "sorry, no warranty or refunds etc.", so royally screwed.
After all said and done, for same total price, could have had a super engine done CA legal, and would still be rolling in it...still learning.
Maybe keep your non leaking possibly rebuilt ride with comfy clean interior that is running fine, not trade it for a clapped out square with lots of things to fix, ($10-15k or more now) just because it has a plow.
Noticed in the square pic, beside other clues, exhaust residue on the body, if it had cats? hmm, no bueno?.
Noticed it did not look "taken care of" where yours does. (hence odd engine, column, windshield, tires, possible trans, axles, gears, carb...yikes, still learning).
Usually means...mmm $20k, and lotsa' headaches, and you give him your truck to boot?.
Rent one when you need it or hire it done, while you ask the guys Here for help finding a "Nice" square to work on, plow with, and for fun.
In the moment, emotions aside, you can get a plow you can afford right now, toss it on what you have, maybe transfer it to the better deal later?.
I have not looked for a used plow, nor know what the cost is, maybe a couple thousand? Might be some shops up there that took a trade in for a bigger plow? who knows...still learning.
Give your wife a big long hug, hot sea salt bath, and a foot rub, make a nice meal just for her so she feels loved, wanted, pursued and more important than a snow plow,...you just saved $20k and your truck, wife is happy and smiling!...we all are still learning.
