By "side" of a trailer do you mean most of it actually being against the side rather than mounted on the Top and on one of the sides? That probably won't work. Vertical antennas mounted directly next to nearby objects causes significant reflections most times also resulting in a high SWR...
I'm no auto expert here and today's modern computer controlling may have an effect as mentioned above - you'll have to do the research on your engine - but back in the day at least most engines had a separate Voltage Regulator working alongside the alternator and they were 14V. A radio buddy...
