Most RV ovens are heated by a propane source. The propane can make for a hotter oven than most people are used to. A great way to help regulate the heat is with a baking stone placed on the wire rack in the over set just above the propane flames . Additionally, you will want to place the rack holding the food you are baking on the highest possible position.
As with any oven you will want to preheat an RV oven before you place your food inside and begin baking. It is a good idea to purchase an additional thermometer to double check the internal temperature of the oven as RV temperature dials are not always accurate.
If you plan to utilize the oven and other features of your RV it is a good idea to know as much as you can about these features and how to use them. Learning these things while on your trip can take valuable fun and relaxing time away from your trip. The more you know and are prepared for before you embark on your journey the better.
If you know the model of RV you are going to rent before your trip you can do some research on it before you leave. You can also ask your rental company for any brochures or information they may have available so you are best prepared and ready to go.
