I think it's an excellent truck for any trade, - - it does seem almost like an absolute necessity for electricians, plumbers, handymen, and 'all-type' home improvement guys like myself, - - that need to carry any number of tools and materials.
Seems like with painting it would be handy, too, - - nothin' better than having the 'paint-store' right out in the customer's driveway.
One thing I can guarantee you, - - when and if you do get a truck like this, - - you'll wonder how you ever survived without it.
They usually come in 10'-6", 12'-6", or 14'-6" long boxes, - - and with choices of 6' or 7' heights. Mine is the 10'-6" length and the 7' height, - - my last one was the 12'-6" length, - - but I find this one more comfortable to drive around town and easier to park at the customers homes. It's not so big they mind it being in their driveway.
One of your other choices are with or without the toolbox doors and bins, - - you can probably save a couple thousand 'without' them, - - but I think it's well worth it to spend the extra bucks now, - - to be able to access tools and such from the outside. The outside boxes on mine also have sliding doors on the inside so you can access from either in or out.
Next choice would be an overhead rear door or 'swing' doors, - - I've got the two swing doors, - - seem easier to open and less upkeep.
Another option is the 'dualie' wheels on the back, - - which I doubt you would be carrying all that much weight for them to be necessary.
You'll need racks on top, - - and preferably a 'built-on' ladder on the back for access. Keep in mind the distance between cross-rails on the racks is directly proportional to the size of the truck.
Mine also has an access sliding door from the box to the cab, - - which I rarely use to go through, - - but it's handy to open it up for carrying 12' boards or a 24' ladder without having to go to the trouble of tying it up top.
Hope this helps, - - gotta go!! :Thumbs:
