Converting a class C from 30 amp to 50 amp service

It's not too hard to switch it. Purchase a 50 amp breaker box and cord and swap out what you have. If you have a generator transfer switch you will probably need to upgrade that to 50 amp as well. Assuming it all fits it's pretty straight forward. I converted a friends TT once and there was plenty of room for everything. I'm sure some RVs would be too tight.
This should be a simple job for an electrician but might be too much for someone with no electrical skills or experience.
