A couple of years ago I put new Monroe shocks on the truck. They were cheap, maybe $35 each.

The truck rides kinda rough. I was thinking about changing to a KYB($50ish each) or Bilstein($75ish each). Would a better shock help much? I also am considering replacing body mounts. Would that help with making the ride smoother? Never done that job so not sure if its doable in the driveway with hand tools. The truck has a little over 190,000 miles currently.

Or do I need to realize its an old truck and stop whining?

I would say all of the above.
If rears you may want to look into springs and shackles.
If the shackles are seized up it will ride rough, and over time can fatigue/ crack the frame.
Switch to poly cab mounts and you will love them.
KYB or bilstein is good.

Interesting. I didn't know that shackles could seize up. I wonder if that's what's happened to my truck. I've been thinking about the OP's question a lot lately, as I'm traveling over some horrible highway road now, on my way to work. I don't recall the truck being this rough when I was on the highway when it was much newer. The truck has been driven in town mostly for the last 10 years.

I've got KYB GR2s on my truck now... that's their low end shock. An they're about 5 years old now. I'm considering putting the 75K miles Bilsteins back on, as they were not worn out, like I thought they would be, when I bought the KYBs.

Wouldn't those make the ride rougher? Why do you prefer them over stock rubber bushings?

No. It rides the same.
The rubber ones deteriorate and cause the holes that they sit on to rot and become enlarged which causes the cab to drop down.
I switched to poly about 8 years ago and never looked back

Are body mounts easy to do in the driveway? I have a jack, jack stands, plenty of hand tools.

Not bad.
have a nice block of wood if you do it at home.
I loosen all of the mount bolts,
Jack up the cab slowly and carefully until the cab mount upper can be slid out. Slide in the new mount, drop, continue to next one.
Once all replaced tighten the bolts.
Worst ones are the ones for the radiator support.
Bolts are difficult to access

New shocks--especially truck shocks--don't necessarily make the ride less stiff--if anything they can make the ride stiffer because they can slow down spring compression. Shocks slow down rebound which can make the ride less "bouncy".

I replaced worn out Bilsteins with KYB's on one of my GMT400's and it didn't help at all. A couple years later I put new Bilsteins on and the truck had a LOT better control. But it didn't make the ride any more cushy. My experience and others I have talked to, Bilsteins are the shocks to have on the GMT400's. Ranchos are good but historically they have a short lifespan. Maybe they have improved their longevity since the newer GM trucks with offroad packages now come with Ranchos.

Body mounts can certainly make a difference. Polyurethane bushings are nice but they can squeak or groan a bit. I have Energy Suspension poly bushings in the A-arms of my 96 K1500 and when it's cold out they groan until they warm up from being flexed. On rare occasion I hear the poly cab mounts make noise.

When I was doing the same, I was kind of "shocked" (haha), that the Biltseins had more resistance than the brand new KYBs. That's why I put them away for future use... they weren't actually worn out.

In the past when I've replaced shocks, (OEM and Gabriel) they were obviously toast... well the rear Gabriels weren't completely shot, but I was done with them... they went to my dad for his 1/2 ton. He likes to run shocks until they just about fall off the truck, for some reason.

I have had several sets of shocks on the Express van. I like the KYB Monomax shocks more than any other shock that it has run. Bilsteins included. With the KYB monomax shocks, 1 ton front sway bar and hellwig rear sway bar the thing handles so much better. Ride is great as well.

I replaced original worn out AC Delco's on my 96 G1500 that runs a maxed out everyday payload with KYB's--didn't help that truck either.....

But I don't think they are the monotubes.
