The best made 5th wheels are also the most expensive; Here is my list of the top of the line.
New Horizon
Continental Coach
Spacecraft
Excel
DRV
Lifestyle Luxury (because of frame only)(Carriage's old frame)
There are other lower priced 5'vers that may fit your needs(Putting those on a list could get hot!), and there are good orphan trailers available.
For the money I could afford IMO Cedar Creek was the best unit with the best - build (my area) and the looks & floorplan (wifes area). IMO the tier under those top 6, there are more expensive trailers but none have a build that is better than the Cedar Creek, maybe some have more interior glitz type items, but the build is most important item.
