I also use a squid pole for some of my portable operation although mine attaches to either the caravan front back via permanently attached vertical tubes. I can also attach it to the back of the twin cab via an adapter to the L-mount normally used to hold a helical HF whip while travelling. I use the vehicle chassis (or van chassis) as the ground plane rather than radials along the ground. I will take some photos of the L-bracket arrangement next time I have it in place and add them to this topic. I already have some van mounting photos but will need to locate them amongst the multitudes.
My squid pole is of the 7M variety so the 7 metres of wire down the middle doesn't make the 1/4 wavelength on 40 metres but via a 4:1 un-un at the base and an LDG Z100 tuner, it will match on all bands 80 metres upwards. It even works on 6 metres.. I have a switched toroidal inductor (or another conventional cylindrical one) that I can include at the bottom that allows me to match on 160 metres too. Not efficient but at least the radio will deliver full power to the "matched/synthesised" load.
Keep up the videos..
