A lot of people use a dual system. It uses a 12 volt battery & 110v shore power panel in their trailers. Mine uses a PD4045 (Progressive dynamics), which provides 110v power with circuit breakers, has a 12 volt fuse block & a converter to step down power from 110 volts to 12 volts. It also has a "stepped" battery charging system, to charge batteries when plugged into shore power. It looks like this on the front side & solves a lot of problems in a nice, neat package. I think I paid about $170 for it, but breakers need to be bought, along with the 12 volt fuses.

It's really the easiest way to sort out 110v power distribution & 12v fuses. If you add a 12 volt battery, your system is pretty good, add a solar panel & you have any option for camping pretty much covered.

PD4045 agreed, unless you go with Lithium. IMHO

I really dont want to use a battery because we camp at campgrounds all the time. Will this same setup still work? Thanks for your reply

Yes. the PD converter will work without a battery, but is probably overkill if you plan to NEVER have a battery. If you are not going to ever have a battery just get a power strip and use 12 VDC "wall wart" power supplies for individual lights etc. Or get a $20 12 VDC power supply off Ebay and wire all your 12VDC stuff to it. But do not ever use those for charging a battery. The power supply will only kill your battery.
