I do not think the OP was trolling. I think he is trying to live a very minimalist lifestyle and asking questions. Whether this dream is realistic or not only he can decide after getting more information. I do not feel it is my place to judge.
I will provide the information I have after RVing for many years.
1. Trailers are not built as well as other types of RVs. In your price range, you will definitely be purchasing a used trailer. You will want to meet the owners and find out how they maintained and stored it. It would be great if you could find one that was stored out of the elements. You need to be very careful about leaks. You want to purchase from someone that was meticulous in their care of the trailer. This will take a lot of searching and probably many miles of driving.
2. You need to create a spreadsheet of realistic costs. Look at what you are spending right now - create a budget. See how that budget would change with an RV. You will definitely need to budget for repairs. You will need to be very handy to keep the repair costs down. You will also need a good set of tools. You will need to budget for electric costs since they are extra when you are staying long term at an RV park. You will need to budget for propane costs. You also have licensing and insurance for the RV and the truck. We have found that the maintenance costs have been higher than we thought and buying used will add to the costs. For example, appliances like refrigerators, microwaves and air conditioners have a life span and are not inexpensive to replace. You will need to budget for new tires at least every 7 years. Etc. Build a buffer into the budget for unexpected expenses. They will happen.
3. I agree with Mr. Mark - consider work camping. There are two of you and for a combined 20 hours per week, you can get a site at an RV park for "free". This would be a great way to stretch your dollar.
4. You had asked about quality trailers. I have not been in the market for trailers for many years but, in general, the higher the initial price, the better the quality. Walk through a LOT of trailers from different manufacturers. If you poke around a lot, you will see a pattern of which ones are holding up better with time and which ones are made with better quality materials.
5. You will be living in the trailer so make sure it is livable for you. We purchased a trailer years ago that we thought would work for us but the floor space was too small for the two of us and one dogs. We were constantly walking around each other. Our necks got sore watching the TV because the the awkward angle. Slides really help with livability.
6. Trailers have small refrigerators. You need to think about if that will work or if you will want to get another way to store food.
Good luck. I hope you make the right decision for you. Please come back and tell us what you decide and how it ultimately works out.
