I think getting rid of that monster dump trailer is a good idea but to get a regular single axle dump will not really help you. If it had a contractors dump then I'd say it will help you. Haul the skid on the trailer and put attachments or supplies in the box and you can still haul bulk materials. I like the idea of the hook lifts versatility but they have such a high price tag and they do weight more. To me they only work if you have all the different bodies to utilize the versatility but again all the money for bodies where a contractor dump will give you most of the positives without all that investment.
Do or do not. There is no try. yoda
