How many people do you need to accommodate in your RV? It sounds like your kids may be grown, and if you have no need for sleeping quarters for multiple people, you can definitely find a trailer that can be pulled with a 1/2 ton truck. Do you already have the truck? If so, determine if it has the factory towing package, and a suitable rear end gear ratio. Knowing what you can comfortably tow is essential before you shop.
A smaller trailer gives you more options for site selection. Since you are already experienced campers, your transition to the RV side will mostly involve the logistics of pulling the trailer, backing in, setting up, etc.
And the first time it rains, you can sit under your awning and watch it fall while enjoying the cold beverage of your choice, secure in the knowledge that your bed will remain warm and dry.
