It would be helpful if one had an idea of what your budget is and go from there. Hard to tell you to buy a Mobile Suites, Teton, Carriage, Excel and on and we have no clue what you plan on spending for your new 5er.
What you'll normally see is those that own a certain brand will recommend their own 5er...nothing wrong with that, I love mine and after 6 yrs, it still looks great and is a quality unit, but again, we have no idea what your budget is.
This topic can be searched on this forum and you will have day's and day's of reading material on which is best and on...All have their good and bad, again, you'll find this out by researching the topic, again, on this forum.
The other side of the coin is, "What are you going to tow with?". Most of the "more expensive" 5er's are also heavy....Thus, you would need a bigger truck, ie 1 ton SRW or 1 ton Dually to tow some that may be mentioned on this thread.
So, two things would help us to help you in your search. What is your budget for the new/used higher end 5er and what do you plan on towing it with...both answers will tell us better how to deliver information to you...:)
