I wonder this becuase I do not want to exceed my hitch limits, or put too much strain on my engine. I know there are many factors that are included in this, like if the leaves are wet and the cubic yard amount. I'm thinking about 7-10 cu. yrds or so.....If any one has any idea, please let me know. I'm also looking for a new trailer to handle this additional weight, maybe a 6 x 12 big tex, but I have never had a big tex trailer, are they any good? Any input appreaciated.
