HelpAdding levels temporary ?

Hello, do you think it will work if i give myself enough rp to go lvl 70, buy a tank and directly go back at my normal level ? or maybe there is a cheat to unlock the tank directly i dont know.

thanks (sorry for bad english)

Why not just make yourself level 70 and stay there?
Use a RP generator it looks sorta legit. (Besides the stars attained).

R* really does not care at the moment.
