Let my 2018 Taco sit or sell it?

keep it! everyone here has some great long term storage solutions get a few moth ball bags then place them all over engine bay and try cedar blocks in cab that will have a better smell inside cab!!! trust me moth balls in cab equals you'll come back and never want to drive the truck again, i put a bag of moth balls in a co workers truck as a prank and they were only inside a few hours and the smell was extremely overbearing he was dry heaving the rest of the day lol!!! but it does keep the critters at bay!!! also the gas if you can get ethanol free gas most racing tracks or speed shops sell it! some gas stations sell it too be careful a lot of those fuels tend to be leaded and a good stabilizer /w ethanol treatment is also a good alternative

 

IMHO, she either drives it or it sets dormant. Driving it is preferable. Starting the engine and letting it idle to warm up is not the same thing.
