Hello I got my technician license. I primarily got my license to use 5 watt baofengs for off road and over landing purposes, though I do have a mobile unit in my jeep that is uhf/vhf 50 watt that I use when I am on the go and much prefer the strong radio and large antenna over the little Baofengs. now I don't think I will ever convince friends/family to commit to that kind of investment into a more powerful radio that is more intrusive in your vehicle. especially since the Baofengs are so convenient and are far superior to CB radio in every way imaginable, in my opinion.
Now the advice I am in need of is that I have a dream of turning my jeep into a repeater for friends and family to use when we are out on the trail, as we are regularly outside of cell phone reception, and once we set up camp you would be able to use the jeeps much larger antenna and 40 watt power source to send your baofeng signal significantly further and if some one decided to go hiking it would be a much more reliable and reach further then the simple baofengs by themselves.
what i have come up with thus far is either getting a radio that performs the function by itself

OR

or alternatively, using this device which seems to be just a repeater in a box that i could then just use an amplifier between this and the antenna

now i am not sure if i am even on the right track of coming up with a feasible solution or if i'm just wasting my time all together.
I also have had trouble coming up with antenna solutions as well. originally i planned on using a 102" stainless steel whip antenna but have recently learned that that isn't even close to the correct antenna to use. but i would like to get a long antenna that could be pulled over to avoid getting hit by branches and then deployed when i need it. the antenna only needs to be for VHF not dual band.
Thank you for your time any advice is greatly appreciated,

What radio do you already have in the Jeep? And you don't need an 8 foot antenna to do well. You'd be better served with a proper dual band antenna, and a good antenna installation; I'm very happy with my MFJ 1412.
Depending on what radio you have, it might have the built-in capability to work as a crossband repeater. Basically, you listen to the UHF frequency, and transmit on the VHF frequency. The truck will be listening on VHF, and re-transmitting on UHF with higher power to hopefully extend your range.
