If you want a very reliable quality splice in a dry application, go with a crimped butt connector or solder them along with a wire nut or heat shrink tubing. Never just twist them and put tape on them. I always use butt connectors in our TT for 12VDC - they're fast, low cost, very mechanically reliable and strong, good for higher currents and no 120VAC needed for a soldering iron. Another advantage of butt connectors is that the wires are inline and take up no extra space compared to a wire nut.
For crimping 3 or more wires together, you will need closed end crimp caps:
A basic low cost wire stripper & crimper like this is good enough and you can leave it in your TT along with your other tools and you'll be able to make splices anywhere while on a trip.
