I need help determing gauge wire and fuse size

I'm adding a 12v plug in the back of my truck and a couple usb charging ports. The 12v plug will be used to run a Dometic cfx3 95dz while driving (once I get to camp I'll switch to my battery generator). But let's just say I also want to charge 2 phones and have the fridge plugged in all at the same time. What gauge wire should I run to the battery and what size in line fuse should I use? I'm thinking the wire will be 26' long tops.
Here are some of the specs for the fridge



And here are the ports I got for the truck along with the links for them. I switched out the 1 usb port for the QC 3.0 one

$18 Linkstyle 4 in 1 Charger Socket Panel, 12V 4.2A Dual USB Charger Socket Power Outlet & LED Voltmeter & Cigarette Lighter Socket & LED Lighted ON Off Rocker Toggle Switch for Car Marine Boat RV Truck

Thanks!

at 10 amps going to the back of the bed I'd use 10 AWG but you could probably get away with 12 AWG

 

So 10.4 for the fridge, I'm hoping that that's the most it draws while the compressor is running? What about 2 cell phones with qc 3.0? From what I can find it's about 2 amps each? Does that sound right? If that's the case I figure 15 amps total and going by that chart @6 gearT444E is correct 10 gauge wire. Thanks!

What size fuse should I use?

 

looks like 3 amps, so you will be under 15 amps total. 10 AWG will be good, add a 20 amp fuse early on in the circuit.

 

So add the fuse closer to the ports in the bed of the truck?

 

Add right after you connect to the battery, you want the whole run of cable fused to protect in case of a short in the wire.

 

Thanks. I thought it should be closer to the battery since that's were all my others are.
