A supercap might be able to start the vehicle, but if your battery is too weak to do so by itself, then it is already discharged to the point that damage has occurred. Supercaps don't solve the problem of battery drain during EOC.
A better solution is to buy a deep-cycle battery, or to install more battery capacity.
If you buy a big enough battery, you can even disable the alternator and charge from home.
