Can't help you with the pole holder, but as regards tucker and 4x4 rangers.
I asked them about 2 years ago if they could do it and they come up with the old we'll get back to you. They then did a demo at a supplier in my area and I asked again much to there embarrassment as it was obvious to every body else that they hadn't looked into it.
I wouldn't recommend using a 4x4 truck with the price of fuel going up like it is but I got mine done by another wfp supplier in the end for a lot less than tucker are offering now and just as good a system.
