Once, probably not. You don't want to subject them to an extremely long crank time.

I carry 2 of the small lithium battery jumper packs. On my 06 GMC, the batteries died when my wife had the truck. I was in the midst of a breakdown repair at work so couldn't leave right away, so she called CAA. The repair didn't take as long as I thought and I arrived 2 minutes after the CAA booster service. His booster pack wouldn't start the Duramax, so I put my big old booster pack on the second truck battery and it started right up.
This experience caused her to want to carry booster batteries for our travels. A major Canadian retailer suggests that their battery packs can start up a 6 liter diesel, so using that and my experience, I opted for 2 of the larger sized lithium packs from Amazon.
So far I have not had to boost my truck. But the lawn tractor, the Honda scooter and somebody elses' truck in a campground in Newfoundland have all been easy starts for just one of the packs.

Not unless they are discharged too low. I have sufficient batteries and sized cabling that I could do mild welding with them.

I carry the NOCO GB70. Have not used it.

I would have no issue using my trailer deep cycle batteries to jump start a vehicle.

Except pulling and re-installing 4 batteries twice is at best an inconvenience. At worst impossible either due to ability or battery fitment.
And depends on conditions. Cold weather, may take both batteries (especially in a 7.3 Powerstroke. Those things are cold blooded). Warm weather, 1 good battery will light off a diesel pickup no problem.
Using camper batteries imo is a last resort type of thing, if they even work.

For the “I bought _____ booster. It should start my rig, haven’t tried it though” folks.
If you’re actually concerned about getting your vehicle started at an in opportune moment, unhooking the battery(s) and testing the jump pack is super easy.

My 2¢ !

Just because you buy a name brand jump box and pay a lot of money for it does NOT mean it is the best value ! NOCO has a good reputation, but not everyone is happy with theirs !!

The opposite CAN be true ! I have great respect for the author of this video and value his opinion New KING of Jump Starters ?

I couple of features I really like

• decent carrying case
• waterproof (with the covers installed)
• built in flashlight
• built in USB charger/powerbank (USB-A and USB-C)
• recharges via provided standard "phone charger" (including ones that plugs into a cigarette lighter( via the provide USB-A to USB-C cord.

For using my trailer batteries it would be with jump cables not a battery swap.

The booster is not just for my use but anyone else that shows a need. Might be a buddy at work or a motorist at the grocery.

Try that out. If you have dead truck batteries, it is doubtful a set of jumper cables from a single deep cycle battery would light it off. And that's IF the truck happens to go dead within reach of the camper battery or you can bring the battery to the truck. Maaaybe, both deep cycles and 2 jumper cables. But again, it's a last ditch effort, IMO and not a universal solution.

I mean, batteries don't usually die in the most opportune setting.
But, with a few options for different situations on board, you could reasonably cover most all scenarios. With RV batteries being one less certain possibility depending on the situation.
Of course jump packs aren't a 100% certainty either. It's situational. Best defense is a good offense and eliminate as many potential reasons that you'd have dead batteries in the fist place.

I use the JNC 770B and it jumped my 6.6 duramax with no issues when It was below zero. I had one battery that was bad.
