Yes, you CAN replace the original inverter. You CAN do anything you want with your camper. The question, is replacing with this one going to give you the results you are expecting? Only you will know that answer after you purchase it and start using it.
Here is a link ... scroll down and read the reviews from people who actually purchased the inverter. When reading, it's best to skip over those folks who just purchased and are thrilled with it. Read the reviews where folks have been using them for some time. Longevity is something I'm sure you are concerned about.
