solar on/off grid installation

i do have a converter in the camper that converts dc to ac. It is just a standard camper converter system.

A standard RV converter converts AC to DC. 120V-> (nominal) 12V. Progressive Dynamics is a well respected brand name for RV converters. I have one that is still operating well at 44 yrs. old.

To really hit on specific advice, share what you have now and how you use your RV. Calculations of power use is especially helpful.

Typically, the output of the solar controller is fed into the batteries, directly. Since even a modest system is producing 20+ amps at 14V or so, cable dimensions should be on the larger side. I often suggest to upgrade the onboard converter wiring to the battery at the same time solar is installed. For those using solar, some also use a generator and squeezing the most out of generator run time with just a cable replacement makes economic sense.
