They're multiplying...much to my wife's chagrin.

Picked up a '98 square body from a guy who was hard up. Got it for 2k. 144k on the truck, 20k on a Goodwrench 5.7 crate motor. It has sat for 3 years and was running rough. Did a tune up yesterday, she's purring like a kitten now. Ac doesn't work and the Pittman arm needs replaced, otherwise it's a solid truck. I really don't need 2 and am having a hard time deciding which one to keep. The 2005 GMC just rolled over 200k but since 2018 I've put a lot into it (u-jounts, rebuilt/beefed up the front end, hubs and bearings, new AC, dual stage shocks, chased down all the CEL gremlins, replaced factory head unit/speakers).What do y'all think? Sell one or keep them both? Not sure how much I could get for either one since I don't think the kbb (or whatever) price would accurately reflect everything that has been done to them (all the work on the 05/new motor in the '98). Any input is appreciated.
