if i try to plug my rv in the garage, the 15 amp  breaker keeps tripping.  is this normal or is there something wrong?

Sounds like a short somewhere.
I have my motorhome plugged in to a 15 amp circuit right now as I remodel the inside.
Ran power tools with the motorhome's outlets and not having any issues.

Is there anything else powered by that circuit? If so, and more important, is anything powered by that circuit running at the same time you plug in your MH?
Try plugging in to a circuit you know has no draw. Will help in a process of elimination determination.

Make sure A/C is 'off' before trying to plug in the RV.  That might trip a 15A breaker if everything else is coming on at the same time too.

Is the 15 amp breaker a GFCI style breaker?  If so, then you may have a grounding issue.  e.g.: The 115VAC heater circuit in the fridge can cause this.

A good way to do this is to turn off / unplug everything if possible in the RV.  Then connect to shore power.  Then start bringing stuff online one by one.  If the breaker or GFI trips when you turn one thing on then you start to get an idea where the problem might be.

Also if it's a GFCI, the GFCI's do wear out. I had 3 bad GFCI's. They kept tripping when the A/C compressor would turn on. With a normal breaker the A/C unit works fine. A new GFCI fixed my A/C problem.

it is a circuit breaker, i will try some of these ideas

Are you sure you are not pulling more than 15 amps? A long extension cord will add a lot of resistance to the equation. You really should be plugged into a 30 amp service but if not then bare minimum 20 amp service with as minimum 14 gauge extension cord.
