My trailer is an 1964 Anderett, it titled out at 1970 lbs. BUT, it has no bathroom or any holding tanks. I did see a nice Holly at the Tin Can Tourist Show in Milford MI. It did have a bath and I believe it was longer too so I'd say it would be a bit heavier, somewhere around 2800 to 3200 I'd guess. Here's a few pic's. Note the roadside door also.
Sorry I don't recall the year.
