i see a lot of these smaller tongue tilt trailer for sale and was wondering how to convert an existing trailer to one or build one? i am sure there has to be a certain % of the load in a certain area for it tilt automatically when a pin is pulled, plus i would need a good latching/release mechanism, any ideas, this is for my bed trailer i am wanting to make. i was going to go hydraulic tilt on it but all the stuff is expensive plus everything i would need would cut into my gross trailer weight. any ideas or suggestions are appreciated, thanks, chris
