Re: Ford Dually convertible to SRW
If you don't want a dually, don't get one.
There are several one ton SRW trucks on the market here if you look for them. I can imagine there are some in your area as well if weight is a concern. A 3/4 ton diesel isn't good for real work other than towing a 5th wheel as payload is limited to around a ton, minus passengers..cargo...hitch...etc.
Doing a conversion can also bring a waft of paperwork and insurance problems. Not saying it can't be done as I've seen a few SRW trucks with a dually bed. Not to say that they didn't buy a dually bed to put on their SRW truck. The biggest concern here is weight. If you plan to run it heavy, you're best not to convert to SRW only because the DOT will nab you sooner or later... Or worse, should you get into an accident and be overweight with either GAWR, GCWR or GVWR you'll get charged for the accident even if its not your fault as you were running illegal.
Axles and wheel spacers are the least of your concern here. Tire capacity is one. You should NOT run tires on dually trucks single on the rear. This is why SRW trucks generally have wider (and slightly taller) tires with greater load capacities. Changing tires will also affect your speedo.
If you do plan to haul heavy stick with the dually and bite the additional cost in fuel and maintenance as you'll save more, even a life or two, down the road.
