Before I read this post, I had no idea what could go wrong with the light trailers. Now, I am paranoid about lightweight TTs. I feel like now I have to buy a heavy TT and buy a beast to haul it around to the tune of money down the drain on gas!
How many on this forum have had issues with delaminating or seams coming unglued in their lightweight TTs?
I have even with proper maintenance but I had more issues with the cheap crappy flooring they put in them which utilizes the luan and styrofoam sandwhich system. I opted to go with stick and tin on my last to rigs and have been very pleased with them. I personally wouldn't worry about my light weight trailer falling apart if I owned one just keep up with the maintenance (as with any camper).
As to using more gas to haul a heavier camper around I'm sure it might use marginally more fuel but the frontal area of your camper has far more effect on fuel economy than the weight! I didn't even experience a 1 mpg decrease in fuel economy going from a 19 foot camper to a 30 foot camper and adding an additional 3,000 pounds in the upgrade.
