MY (note personal preferences) basic changes to his install...dual battery is a good idea if you run more than an HT from the car. Not a fan of the VHF/UHF antenna but your mileage may vary. Don't run the antenna in a metal box. Not a good idea as the antenna won't tune right. Get away from the metal car port and then adjust.
He did try to change it up a bit though via inflection. There was really really well. Really REALLY well. REALLY really well, and I think maybe even a really really WELL in there somewhere. Ditto for the very very goods.
I like Jeeps and I'm a ham, so overall I enjoyed the vdeo really REALLY very very much.
