I ended up buying a Rockwood TT after a coworker retired, bought a new Rockwood & truck, then traveled all over the USA & Canada. Two years of fulltiming more than 6 months out each year, I looked at their TT again. Jeez, it looked NEW. Holding up very well. They've now had it over 4 years, and have dragged it countless miles. Still holding up VERY well.
So we bought a Liteweight Rockwood. Had it two years now. Great TT. Here's a couple of pics to show some of the construction:
Bed support aluminum frame in the forward storage compartment:

Go see one yourself, climb underneath, inside the storage compartement, and open all the cabinets. Our 25' TT weighs 3576 lbs empty. The delivered weight, with all the options, was 3993 lbs. Lots of welded aluminum square tubing used throughout the box construction.
We think our Trail Lite is made well & is considered a lightweight TT. You may be able to find a used Sunline TT that is light.
We did have a HTT JayFeather that was NOT well made. In fact, it was so BAD it had to go back to Indiana as a reject due to ongoing leaks & delamination.
