iCom IC-2730A is what I have installed.
As you already know, I have dedicated power and ground ran into to the cab and hooked up to a blue-sea fuse block with ground to power various things, including the iCom.
I then ran the antenna out to the SDHQ ditch light bracket, and used Rago Fabrication HAM antenna mount that I took off from my 4Runner. Works like a charm. Yes the antenna does get bendy but after 2 years of driving various distances and speed and sending it in the desert the antenna and antenna mount both held up just fine. Did not get loose or bent at all.
I use ICS Dash Mount and drilled a hole on the dash (under the rubber tray, which you will not need with dash mount) to run the display panel cable, and mount the display panel on the ICS. I took off the head unit to run the display cable, hid the wire under the floor console/ storage, and hid the wires under the all weather floor mat since hiding it under the carpet was pain in the butt. Also the OE all weather floormat hides the cables pretty well.
I run the speaker for the iCom on the passenger side of floor console using a 3.5mm headphone extension, and put the mic on the driver side of floor console by my leg with a 6ft CAT-6 LAN cable extension. I routed the 3.5mm extension under the floor console, and the CAT-6 under driver seat. Everything is hidden.
For the brain of the radio, I made a custom mount and wedged it under rear driver seat. That houses the fuse block, the HAM radio unit, and Victron DC-DC charge controller. I used a velcro to attach the HAM unit to the mount. When I put the seat down, everything is covered up nicely.
