Is your RV's shore power connection 30-amp, or 50-amp? Each uses a different receptacle and, obviously, different wire and circuit breaker size.

I did this for my RV, which uses 30-amp shore power, so that's what I'll describe:

To connect to your house panel, you'll need a 30-amp, single pole breaker. For the conductor I used 10/2 UF wire, which is approved for direct burial (burial depth varies by local code - I buried mine 24 inches). You can also use individual conductors in conduit, which may be more expensive. The receptacle you need is unique to RVs; it is a NEMA TT-30R. Places like Lowe's and Home Depot may not carry them. The easiest thing to do is go to an RV place, where you can buy the receptacle mounted in a weatherproof box.

I know this is a DIY site, but the way you phrased your question suggests to me that you don't know much about electricity or electrical work. If that's not the case, I apologize. If it is, then please have somebody help you who is familiar with it. This job is not complicated, but can be dangerous - parts of your breaker panel will be live even if you open the main breaker.

If your detached garage doesn't already have a sub panel in it...
plan to do that as the first part of the project.

At that point... one more circuit in there will go to the RV (30A/120V) receptacle.
Easy peasy.

eta: There are about 200 threads here on how to do the garage panel.
