I've made a bracket and mounted a 4' fire stick 2 ( screw adjustment type) in front of hood. Now the vswr is 1.5 at channel 1 and 1.9 at channel 40. While not great, that's the best setup I've seen.

I think without some kind of Frankenstein setup on the truck this is as good as it gets.

Also my radio has been giving me a bit of electrical noise (whine) on the higher channels since day one, what can I do to mitigate that? Would a choke on the power wires help?

I've moved the mount to right in front of the hood. Now I've got SWR of 1.8 at 40 and 1.8 at 1 with no spring and adjusted all the way down ( friestick 2 screw type adjuster). Might be as good as it gets...

Sounds like bad grounding on the truck or bad coax, try a different coax or build one with new ends and see if that fixes the issue

Ok tweak that screw on the the fire stick and see if you can get it to a 1.2 on 20 then you will be set

I'd like to again thank everyone for their kind help!

I've tuned the firestik all the way down with no nut and then cut off 1/4 inch of the screw. This results in no change in SWR . But hey it's below 1.8 and I guess that will have to do

Yes and boy does it whip? I use some Paracord to tame it while driving toes to the ladder rack.

Issue is ground plane. I have a E250 with ladders on each side. SWR blows. running a 102 inch whip on top of the van with a 4 inch spring I have to go to 29.000MHZ to get a fair SWR. 27.000Mhz It will work but its over 2.25-2.50. Ladders crap on everything. Make the wave go nuts.

I have the parts to boost my stuff up more, maybe you will want to try it.
Damn trees.....
