I'd hate to have to have you do that.
Since it's a mag mount - set it up like you did on the other vehicles.
Only try to keep the whip in the base in a same tuning spot you had for them, your other vehicles.
But, just for verification - try it on the roof - if the SWR is 1.5 or lower that's all I needed to know - for the issue would be due to lack of a way the RF energy can generate the counterpoise image from the RF propagating away from the whip at that spot You Want To Put The Antenna. Think of it - like a tuned string - pluck it in the wrong spot it will still "vibrate" but it takes a lot more energy to strum the string to vibrate - than it would take to strum the string where the easier and less effort it takes to accomplish that same task - try thinking of it that way when you try to find a good spot on that vehicle
It has been my philosophy to say "Just because the antenna looks cool at that spot, doesn't mean you will get the best performance from that Hi-Po miracle of an antenna - at that spot on the vehicle. You need to provide the best location to obtain that expected level of performance. .You achieve that by looking out for, and utilizing where, to determine how well the antenna will resonate at specific locations - and that is to use your SWR meter to help determine the best locations by finding locations on the vehicle that provide the lowest SWR for that antenna UNTUNED - as in just put it together correctly but not set.
How does that work? Well I explain it this way...if the antenna is given a good location - it's going to resonate over a greater range of bandwidth - which equates to a lower SWR from the start of your whole install process...which is where the antennas' performance will be determined by the location and how well you can make the install work from that location.
