Ultra light TT

X3 Lance.

X2 on Lance

They're more expensive than the average trailer, but they're 4 season rated, built with a composite which can't rot like wood does. They are also ultralight (they use the same kind of wood used in corporate jets. I got all this info from their website! They also have a 2 year warranty, not every company has that

Here is the factory tour of Lance

We like our Rockwood 2104, but it appears they no longer make them. Rockwood does have a "mini-lite" 2304 that might fit the bill.

I believe every manufacturer has a lightweight brand.

We are on our second Fun Finder -- well-made, well-insulated, light, and not too expensive. But our manufacturer, Cruiser RV, just got bought by Thor (which makes Airstream), so we will see what the future holds.

You might want to take a look at some of the fiberglass "Eggs". I have a link to the different manufacturers here. (Scroll down past the blogs). Sizes range from 13', 1000 lb trailers to 25'. I have an Escape 17B, 17', 3010 lbs loaded for a trip with a tongue weight of 350 lbs.

While expensive, they are very light for their size, and extremely durable. I've attended rallies where the oldest trailer was over 40 years old.

Take a look at some of the Lance Trailers:)
