The answer to your question is really much more complex than what may appear to you. Every brand of camper brags about being "lite". But, "lite" compared to what? And where is the limit on the over all weight you can comfortably pull under extreme conditions. Yes, "extreme conditions". Any vehicle can pull just about anything, but when the conditions are less than favorable, some vehicles pull some trailers much more comfortable.
What is "best" and "good" for one person may be absolute trash for someone else. The length of a camper across different brands may be vastly different in weight, and the same floor plan across different brands may appear the same, but when you add color, fabric, flooring, and the actual materials used, one camper, identical floor plan, to another camper, may appear to be totally awful.
Then there is head room, flat ceilings, and arched ceilings, 30 pound propane tanks or 20 pounders. Holding tanks have different sizes. A gigantic trailer may have only a 32 gallon fresh water tank, a little bitty one may have a 50 gallon tank. Add water and the weights of the over all camper change drastically.
And as stated above, not knowing what type of camping you intend to do (boomdock, State Forests, State Parks, Private, or permanently placed-seasonal), mountains, ocean, or prairies, Northern States, Alaska, or Florida, all will make a really great working camper in one region of the country completely suck in another.
Lots and lots of factors to consider.
Every brand is "best" ... otherwise they would not sell. Every brand has problems. And every brand requires diligent maintenance and upkeep on them if you plan on keeping them for longevity sake. They take work and effort to maintain, ... all of them, otherwise, they become junk REAL fast.
What you really need to do is get out and visit RV dealerships and visit RV shows and start window shopping. Your experiences are like a blank notebook right now, you need to start filling in the pages for what kind of campers peak your interest. THEN ... you begin to have an idea what you like, and THEN posting those choices and asking for opinions and advise on them, well ... we all can give you our "wonderful and expert" advise! ๐
