Vehicle based, what kind of range can I expect? Will be mostly over flat ground. Is there anyway to boost range? Im a total newbee to CB , had a home base in the 80's but didnt really get technical about it all.

with a decent set and a good ariel set up , you should nt have any problem with distance , depends on how far you expect to get with it . i`m on mersey side and regularly hear a couple of geordies , they could be any were i know .

I would obviously like as much range as possible, I plan to have one in a vehicle and one as a home base, even going to the nearest shop here is a good 5 miles away so range is important. The home base is undecided but the vehicle will have a firestick mounted on a bull bar, not ideal I know but I need it to be rigid as its a soft top it can only go on the bull bar.
Is there a way to increase the 4 watt output?

Legally, no. CB is limited to 4w. If you have no qualms about legality, have a search for "CB burners".
Make sure you have decent antennae though, no use putting out 20 watts if the antenna is crap.

Is SSB worth getting? Also, I see radios classed as ''import'' , I take it they are 10 meter?

Firestik are good antennas pretty tough and the 11 later model a doddle to swr. Mounting on bullbar will work but at a sacrifice on signals in some direction .
If you imagine a round tin lid.you put a antenna dead centre you will get equal radiation and signal receiving equally all around.
Place the antenna on any edge it will decrease in the areas where less surface area between antenna and edge.

Same with bullbar.
What length firestik you got ?.longer better. 're increasing c.b Radio 4 watts .to increase it is illegal however I know very few who dont.
I use a sirio 4000 on all our transport .As c.b. Give 4 watt generally it's perfect to feed into a rm kl 203 linear amplifier.
These are rated 100watts am fm. 200watt ssb.
10 watt max input am fm, 20ssb although I believe had been lowered on new models.?
However inputting such may blow the mosfets.
I only input 4 /5 watts am fm and 15 max ssb.
Add a cooling can on top.12v psu cooling can .
You should get a healthy 60/70 watts then and run all day.

Whilst many say cb won't work far I never have a issue 5 miles is easy in most situations mobile.
A decent am fm multinorm will be ideal.
