The small gauge wire and it's length between the batteries is fine for charging in either direction over a number of hours. But it cannot handle the very high amps and voltage drop required for starting from the house battery.
About the camper batteries powering the truck. The camper dealer once told me that the batteries are just wired together. Specifically he said when plugged into shore power the engine battery is being charged. That's all I know. There is a battery disconnect to prevent the camper from running down the engine battery but I thought not in the other direction. But above posts say with the distance and wire gauge the camper batteries won't be able to turn the engine. Interesting idea whether you could physically move a camper battery to the engine compartment to jump the truck.
Now here is a real laugh. From hints above I just googled and the Walmart I was stuck at has an Auto Care Center that was even open on Sunday. I could have asked a mechanic there. Oh well, I made it to my destination campground in West Yellowstone only 1 day late so all good.

Ford uses a switched power connection to the trailer plug. Only when the ignition is turned on is there a connection between truck and camper batteries.

My understanding is that the camper batteries are connected to the engine batteries. There is a shutoff which prevents the camper from running down the engine batteries, but I thought not in the other direction. So if the engine battery is dead I would think the camper batteries would turn the engine. The camper batteries are showing fully charged. But maybe deep cycle camper batteries don't have enough cranking power to turn an engine???
