This might be scattered as im adding in as i think about it.
Main thing to look at is roofs for any unit. Almost all older were rubber roofs and didnt fare well and would leak. If you find something with a fiberglass roof your golden.
If your getting a travel trailer you can still put a golf cart in your bed for the track
One of the most important things is weight weight weight! When looking remember all the # you see are dry weight. Thats no propane no water, no waste water( pooooooooo) and none of your crap. Very easy to add alot of weight so make sure your not even near your max towing when its dry weight.
What motor is in you ram?
Fridge. Make sure you have a duel power fridge meaning can run off electric or propane.
Generator built in is not a big deal as you can get a portable generator for cheaper and still be able to run appliances. Honda makes some great units that you can even run 2 of then together if needed a ton of power.
Do you plan to always be at a campground? If not holding tank size for your gray water(sink shower) and black tank (waste pooooo) is a big factor as this will
Camping is amazing i grew up camping. Started from a tent ended with a 38 foot diesel pusher with 2 slides lol.
Travel trails don't seem to lose a ton of money but motorhomes they do tend to as they are just like a car as the miles go up, the value goes down.
Motor home is going to be a significantly higher expense to purchase over a pull behind travel trailer. It does have its trade offs.
