Do you think I can use this to build a teardrop trailer? This is a GREAT site! Hope to start building in the spring. Thanks for your time. Chopperjoe

Hi Chopperjoe,
Can you build on a boat trailer frame? Certainly! That's what I'm doing although it's a tradeoff. I found that it was more work to rebuild my trailer than it would have been to start with raw materials. the boat frame was heavy so my tear frame is heavier than I would have liked.
If you have the trailer, go for it!
