Don't mix red and green coolant. Pic one or the other and use that.
Walmart sells universal antifreeze that is almost clear which says that it works with everything. Switch to red when you get back from the trip. Better yet don't do anything until you get back. In the unlikely event that you have a problem there's bound to be some universal antifreeze nearby.

Should I switch to red and use that going forward? Once I switch it of course.
I had the green/yellow coolant when i bought my rig. Ended up flushing the system and putting in Toyota red.
"...when you do mix them, then when you use any of the machines that mechanics use to see what the freeze point is, you’re going to get inaccurate readings. So if somebody tries to check to see if you have enough antifreeze in your system, so it won’t freeze in the winter for example, your reading might be wrong. If it gets really cold, you might end up cracking your engine. So basically, you’d want to stick to the coolant that the car was made for.

so is the Toyota red antifreeze an ethylene glycol type?
I used to sell bulk automotive fluids, the OLD GREEN coolant does not have the correct anti corrosion inhibitors and is of a different type of coolant meant for cast iron blocks and cooper radiators.
Universal coolant is a OAT (organic acid technology) coolant, it is good for anything, aluminum, cooper, brass...it will last upto 5yrs OR 150,000 miles.
The Toyota Red coolant is a HOAT (hybrid organic acid technology) coolant, it is made for anything as well and is actually a mixture of the old school green and the new OAT.
Coolant can be any color, manufactures have different colors to scare you intotaking it to the dealer for service.
You can use any coolant you want in a all aluminum cooling system EXCEPT the old school green, which is now labeled "classic green".
I use Prestone Universal 50/50 premixed, it is $8/gal. I use it in my wifes Kia Sedona, my Cruiser, used it in my Corolla, Land Rover...pour it in and go.
I do a drain and fill every 2 years for peace of mind and I have never had any corrosion issues...ever.
So, if I were you, I'd flush out whatever is in there and switch over to either Prestone or Zerex universal.
