Just about to install a HAM radio into my new 2021 LT Trail boss :)
I believe the best idea is for me to run the antenna cabling through the passenger side firewall.
I have some lume tubing and will run it through the spare grommet on the side of the main grommet wiring passthrough.
What is the best way to seal the lume plastic tubing with the rubber grommet/nipple?
Any advise will be highly welcome.

Maybe try a hardware store. Electricians use a putty to seal conduit.
Where did you mount the antenna?
I'm trying to figure out how to mount a Yaesu FTM-300 in the 2021 LT Trail Boss.

Thanks Don, I'll look for some of that. Sugru was another thing I thought of. I'm mounting an NMO antenna base using a lip mount (midland gmrs brand). I'm using 3M underneath it and then routing the wire left and down through the passenger side firewall grommet. I'm then going to pop off the upper dash cover and install a SO239 dual female panel insert. That way all my antenna wires will stay nice an stealthy out the way. As for my radio I bought a case from powerworx that mounts with a small power supply underneath the radio. It fits into the console and I'm using the 120V plug in the dash. My radio (anytone 578) has Bluetooth so using that for mic/speaker hookup along with a Bluetooth ptt button on the steering wheel. I want to be able to keep things stealthy and remove the radio when not in use. Oh I'm using a small 9" compactenna and I have a Tran rain cover when not in use.

Traditionally I drill a hole for an NMO mount in my roof but this truck has a sunroof.
I'm looking at using a lip mount also. About the only solution I can come up with right now for the antenna.
Mounting the radio in the truck will also be difficult.
I have a full console and like all the space that comes with it.
I'm not willing to give any of it up for a radio just yet :).
Sounds like you have a plan.
I wasn't aware of a grommet on the passenger side. I've only had my truck a few months.
Good luck on your install.
