1. How difficult is it to find dumping stations - and water refilling stations - and how expensive is it to dump and re-fill?
Where? In the West, not that difficult or expensive.
2. How bad will gas mileage suffer from pulling - even a light trailer - 2500-3500 lbs?
Your TV gets what MPH now? How fast will you drive?
3. How do you keep the trailer from getting stolen - I assume there are hitch locks out there - and how to keep from getting broken into - I assume there are wireless gadgets with phone notifications. There will be many "venues" that will allow me to park there during the event - and even all day - but I assume tat over night will not be an option. Walmarts that are open 24hrs?
TT theft isnโt that common. Park sensibly. Parking all day in any business lot while you go somewhere isnโt nice. Think of the business owner. Think of the homeowner in front of whoโs house you parked.
4. Renting a campsite every night is too costly and would make the whole endeavor impractical. But I'm thinking I would only need to park at a campground occasionally - Once per week? Once every 2 weeks perhaps? (One person)
With a senior pass many USFS and BLM sites are $12. That isnโt costly. You can be thrifty without bothering others.
