In my opinion anything as expensive as a new camper trailer warrants the safety factor of 4 tires(two axles). Camping trailers tend to be a little more prone to flip than a utility trailer if you have high wind or a blowout. In my opinion the only new smaller camping trailers that are built well enough to last are close to $25,000 and closer to $55,000 in today’s market which is just crazy. Few if any sold below that have good reputations for good customer satisfaction. One of the reasons I started building my own even though I am a lousy woodworker and lack the patience, tools and skills to produce something acceptable to others is mine don’t leak or easily break and if they should they are easily repaired. This is all necessary if you are going to spend less than $5,000 to $7,000 and live in it. This is why so many have converted cargo trailers as well. Last time I looked $16,000 to $20,000 was the price for lower end trailers in that size. Prices have gone up due to Covid 19 and now is not a good time to buy an RV period. I would recommend waiting till the market settles then buying a used one. The fiberglass trailers seem to be better values as they have better resale and are less prone to roof leaks. Older ones need to definitely have their tires, frames and suspensions checked as most are single axle and have been know to fail but if you can fit in them seem to have the least problems.
