I'm sort of confused on what to get.
I have no solar. Need one that will get me through a four day stay at least.
What's your suggestions ?

Lots of good advice above.
How much you need is of course personal. However, there is some advice I can offer.
If you always camp connected to shore power, You don't need much.
If you dry camp or boon dock, you need quite a bit.
LED lights, water pump, refer on propane, water heater on propane, and charging cell phones does not require much.
Add furnace in cold weather, charging computers, and maybe a CPAP machine and you may need more.
We run all of the above. We have 200 amp hours of Marine AGM deep draw batteries. It lasts at least three days in freezing temperatures. It lasts 5 days in mild summer temperatures. There is a substantial reserve at the ends of the times listed.
I installed two 100 amp hour AGM group 31 batteries. A 50 amp converter/Charger would charge fast, so if you use a generator to recharge you would need a charger that big or more.
I use a 30 amp WFCO charger. It works fine using shore power for recharging.

This is a good article, but its recommendations against “Marine Batteries” does not apply to “Marine AGM batteries”.
I wish you good luck and happy trails ahead!
