If you have RV parks and campgrounds in your area take the time to go visit them. You will find people with large and small trailer and motorhomes and slide-in campers on trucks. They will be happy to talk to you about what they like or dislike about their current setup and about what they had before and what they plan to buy next. Most will be happy to have you come inside and look at how they have the sleeping area setup and the kitchen and storage and electronics.
It will be a lot more real than reading forum posts. Do the on the ground research first and then you will be in a position to ask questions and get information from the answers. At this time you do not know what you do not know.
