    Hey guys I'm wondering how big of dump trailer you guys think my Nissan Titan would be able to handle. It would be used for mulch and shrub trimmings and maybe rock every great while. I considered selling my truck but I love it to much and don't have the cabbage to buy a dump truck otherwise. I figure 12-14' is about all I'm going to be able to get away with. My trucks tow capacity is 9500lbs. I know I have the ponies to pull it but don't want to tear something up doing it.

    Honestly I would go with a 5x10 5000lb single axle for your truck. It might be able to handle a 5x10 tandem 7000lb but I wouldnt push it. I have a 6x10 10000lb brimar tandem. I pull it with my GMC 2500HD and I wouldnt even try with any smaller of a truck. Your truck may be rated for 9500lb but it isn't meant to pull that often, or deal with the tongue weight of a dump trailer. If even if you go with a 7000lb, you will certiantly feel it when you load it up. Your truck will probably sag way down and the tranny will struggle.

    I dont know much about nissans but I am speaking from experience with an f150.

    I figured if I went with a bigger one I wouldn't be able to load it down with mulch but it would be nice to have that extra room for when I trimmed shrubs or had limbs to pick up. I'm not sure how much mulch weighs per yard either. I know it all depends on how wet it is but I'm sure it is pretty heavy. I thought also I could beef up the suspension also if I had to.

    I would also think a tamden axle trailer would have less tongue weight since it is splitting the weight up on two axles vs just one.

    With a half ton truck, I wouldn't get bigger than a 10 footer. Dump trailers are so heavy!!

    I would get a 6x10 with 3.5k axles. No need to get a heavyduty trailer that you can't use. I think the bri-mar this size is around 2600lbs, giving you about 5100lbs of load. Most mulch will be around 800lbs/yard.

    I have a 6x10 that I can get 8 yards of Mulch in. Ive pulled it with my dads silverado 1500 before but would not do it often.

    You are a little high on the weight. A 6x10 7k brimar weighs about 2100lbs. My 6x10 10k weighs about 2300lbs.

    I agree that their is no point to a getting a bigger one if you can't load it up, unless you are planning on getting a bigger truck in the future. 8 yards of mulch would be a little much for a 7k trailer being pulled by a half ton. The load would weigh in at about 6400lbs which would be 1500lbs over the gvw of the trailer. I would stay with 6 or 7 yards max if your muclh weighs around 800lbs per yard. Mulch can weigh up to 1200lbs per yard depending on the product and the amount of moisture.

    Recently bought a very slightly used 5x8 5200lb single axle dump. Been looking for a long time and saw this little guy for a pretty good used price. Have borrowed a friends 6x12 12000lb trailer often and had it maxed with dirt. From my limited experience it's really easy to overload the larger trailer with heavy material even if you don't mean to. Makes for a puckered ride to dump place.

    I have a 3/4 ton pickup and wouldn't want to haul the larger trailer around all the time loaded to the max. I put side boards on the 5x8 so if my math is correct, it holds 4 yards of debris or 2 of rock. Payload of 4200 lbs because of the 1000 lb tounge weight + 5200 lb axle. Dumps seem to have a heavier tounge weight than regular trailers even when empty.

    Overall, for the price I'm happy with the 5x8. But it also suits my needs. If needed I can always borrow the larger trailer again but I don't see myself doing that. 4 or 5 yards of brush and debris packed down in the 5x8 (with side boards) is quite a lot and if large amounts of rock are needed, I'll just have it delivered cheaper than I can get it myself.

    Not trying to be a jerk. But a dump or any decent size dual axle trailer will destroy your pickup over time. Diesel 3/4 or 1 ton TRUCKS are made to haul. Bigger trucks have better brakes and the list goes on. Do yourself a favor and upgrade to a diesel (or if you prefer gas) 3/4 ton at minimum if you plan to stay in this business.
