I'm getting ready to start my Harbor Freight trailer project. I have one on order. The store didn't have what I needed so I got a rain check for 15% off the sale price. I was wondering how much longer should I make the tongue than it is now? And is it customary to remove any of the leaf springs? I was thinking there were multiple leafs. Also what other flooring options is there besides going with the diamond plate metal? I'm just looking for ideas, and gathering parts now and should be ready to build as soon as the trailer arrives.....
