We knew someone who had Travelong and they had a lot of problems with the gate latches. They may have fixed that by now, but sure something to check on.
The best, toughest trailer we have ever owne was a Swan. They stopped making them a long time ago, but what a trailer. Heavy though, because they were so tough.
There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.
