</font><font color="blue" class="small">( With steel and fuel prices what they are today I figured it would be cost prohibitive for materials/labor/ fuel/electric etc. for me to build a new one. If your a good fabricator, you could probably replace your MH brakes with the brake kits sold at TSC stores. I needed a bigger trailer so chose not to go that way.)</font>
George makes a very good point here. I am a very proficient welder, and several of my family members work every single day as fabricators and welders. In the past, I've strengthened my trailers, replaced axles, strengthened tongues, straightened bent trailers etc. However, as George pointed out, with material prices skyrocketing up, if there is any chance that you may need a larger/better/newer/stronger trailer, if you can, now may very well be a great time to do so.
I bought a 20' heavy duty gooseneck trailer with a 5' dovetail complete for less than what my parts cost would have been. This trailer has 12" I beam frame running down each side and up in the "gooseneck" portion. By the time I priced the same sized steel that was used and axles and brakes, I had already reached the purchase price; and I hadn't even gotten to the price of the bed, wheels and tires, or wiring! There are some great deals to be had if you can possibly swing a new trailer.
