Ability to do maintenance on truck?

1) ask the company.
2) unless its a small mom & pop business, the company will limit your maintenance involvement to just the PTI.

I wouldnt worry about it.

 

I wouldn't do any more than the basic fluids and lights unless they were fairly compensating for it.

 

I worked 3 years for a construction/dump/asphalt company. Generally, they prefer to have drivers that are ‘not afraid to pick up a wrench’. That meaning, on a rain-out day, if you want hours, you can help out in the shop, if you notice a headlamp or signal not working, you can remedy the situation. Maybe a couple times a week, crawl under the truck and grease the power take off. Are they looking to hire a certified mechanic(or Mr Goodwrench) to drive full-time? No.

 

That means, for a day or so someone is on vacation/sick/injured, and you and your truck are assigned to cover that slot on the ‘alpha crew’. Well lo and behold, alpha crew is assigned a residential driveway dig out. But normally you haul sand loads all day everyday, well guess what buttercup? You are gonna be on the operating end of a spade shovel for that day(or three). Don’t fret, you will survive, manual labor never killed anyone.

 

I know when i did dump and bottom dumps , PTI 's were everyday things and if the part was avalible to fix it with , ( easy stuff like flaps , lights , etc) then i'd do it and off i would go . As far as heavy duty stuff ( tires , oil changes , what i call big tool box items ) then the paid mech does it .
