Read a lot before buying anything. Pay close attention to weights, know the difference between GVWR, GCWR, GAWR, Cargo Carrying Capacity (CCC). Pay no attention to published RV weights, only consider the weights on the yellow sticker. This represents the actual build weight.
Buy used -- pay for an independent inspection before closing the deal. In my experience RVs depreciate even quicker than new cars. Many people get in, spend a bunch of money, only to find out it isn't for them -- buy their trailer used at 1/2 or less. Plus there are those who buy new RVs every couple of years -- buy theirs used. And lastly I know not one person who first RV was what they really wanted. Folks don't know what they don't know, us included, sold my fist TT in 25 months to buy the next "right" trailer.
There are a lot of good quality relatively new USED trailers to be had a much better prices.
