We know a little more now. I'm going to jump to a conclusion. Take it for what it's worth.
Given that you currently have a 1/2 ton truck, I would suggest getting a used travel trailer to start.
You should be able to pick up a 24-27' TT for $4-6k. The big thing to look for is no signs of leaks and check that all the systems are operational (get it hooked up to electricity and run them). Search the forum for tow ratings, there is more than the 1 number you need to consider and make sure you are within the ratings before buying.
This gets you into the game for not a lot of money and short of buying a total dud, you should be able to get out with little or no lost money. Then in a year or two when you are more knowledgeable and have some personal experience, you can decide if you want to move to a different RV.
