Losing coolant

I just got an oil change and battery, butnoticed a burning smell after my drive home (about 20 miles). Not too strong, but definitely noticeable. I brought the truck back to my mechanic and had him take a look. He checked it out and said that there were no oil leaks. He did say that he had to add a half gallon of antifreeze and suspects there to be a coolant leak. Now, I top off the overflow every two months or so for good measure, but now it seems that I'm losing more coolant than usual.
As for any other symptoms, I am not running hot, there is no foam or coolant in my oil and I'm not blowing any smoke. About 6 months ago, I did overheat due to a faulty overflow cap. I replaced the cap and everything was fine.
Also, heater core, water pump, o-rings were replaced about 2 years and 25K miles ago. No coolant on passenger side floor.
If this was any other car, I would have the mechanic pressure test the system, but I didn't know if that was possible with the RR's cooling system. Any thoughts would be appreciated. Thanks!

Well, I went to a different shop on Friday to have the cooling system pressure tested. They had my truck for an hour. I was told that my system was holding pressure at 19lbs. They also said that there are no "obvious leaks." When I explained that I was more concerned with the leaks that were not obvious, I was told to monitor it and see if it gets worse.
That being said, I am certain something isn't right. I'm losing coolant and there is an odor which seems strongest on the left side of the engine compartment. Any thoughts?

Hi:
Very new to this forum...quite a source of information! Many thanks to all who post on here with helpful insights. We (my wife drives it mostly)...have a 03 Disco which just turned 85k miles...It has been serviced as required. We run all synthetic in diffs and oil if that matters at all. I have limited mechanical ability in that I can change fluids, plugs..but not much more.
We have noticed of late that it seems to be losing coolant. I have checked for leaks etc. and find none. The oil is not milky at all...and the temp gauge is dead on the middle after warming up....no abnormal white smoke either. I put about a half gallon of Dex-Cool pre-mix in about a week ago....just put the rest of the jug in today....that seems like a lot to me?
What else could be going on? I looked around the TB area to see if perhaps it was leaking there (valley pan?)...didn't see any obvious signs? HELP PLEASE?

No to all 3 questions...thanks for the reply. As you can likely tell by my post...I tried to read up a bit first before posting to see if I could rule out certain things.
I will keep a close eye on both coolant level and oil dipstick/cap over the next week or so.
I know these things have a reputation for burning some oil...but coolant? Any ideas on that? Do they burn coolant at all? Where I had just topped it off ...and then the need to refill with the other half of the gallon so soon....got me nervous...maybe it was just that low? Although I did have it flushed and refilled at a shop about a year ago....maybe they didn't refill all the way?
I hear no gurgling and it heats correctly so I ruled out the need to rebleed...it also heats well which argues against a bad thermostat...not to mention...where did that coolant go? YIKES!
