I you have the experience to identify and evaluate a 5th wheel. Then buying used is OK. But if you lack the knowledge and don't know what to look for. Or even what you are looking at buy new.
THere are bargains to be found on the used market, there are also plenty of leaking money pits. If you If you have the knowledge you'll be fine.
If you lack the knowledge by new from a reputable dealer.
If you aren't familiar, you can always pay an RV tech a couple hundred to go over the rig (once you think you found a good one). It's not a guarantee but should cover most obvious issues and the cost savings going used will more than make up the cost of the RV tech. Also google RV buying checklists.
There are a surprising number of new units that become money pits or get tied up for months waiting on warranty work, so don't count on buying new eliminating all issues.
