1)i have silverado 1500 crew cab with long bed like 6 something cable wasn’t long enough to reach rear tire so i had to move to rear seat cigarette lighter plug2)doesnt deflate the air so if your tires at 40 psi and u wanna drop that to 35 coming off storage this doesn't drop it it stops when u reach to 35 from lower psi but wouldn’t drop adjust dropping down to 35 from 40other than that so far great but i don’t think it will last long enough for everday use or or to fill up a other thingsstill good enough for me
