Weight Capacity of P30 Grumman Step Van

Hello all!
I'm new to this forum and am in the process of procuring a car for my food truck business! I found a step van that is a 1993 GMC 25' feet Step Van. The nature of my business is ice teas/smoothies thus only having a 3 compartment sink, ice machine, sandwich prep table and two prep tables inside the truck. One big difference from regular food trucks with mine is that I am going to install a 200 gallon fresh water tank, as well as the appropriate 15% bigger waste tank under the truck. Now I'm just wondering if all of this would sit well on the step van. I know they are made to transport heavy materials, but will it withstand the water tank with 3 people and the equipment on top as well? I've tried looking around, but can barely find specs on any of these step vans. The most I found was a person saying that a 16' or 18' p30 could carry 8,000 pounds, but I couldn't find the evidence to back me up. Thanks for looking at my post and hopefully some of you food truck veterans can help me with this question!

I would say the GVW would be in the 14-16,000lb range.
Dual rear wheels?    454 engine?
Is the van 25' overall length?......They are measured by the cargo area from behind the seat.

I'm not sure what the engine is, but it does have dual rear wheels I believe. It is 25' overall length.

Why in the world would you want a 200 gallon fresh water tank, as well as the appropriate 15% bigger waste tank in a SV? By the way water is 8.34 per gallon so 200 gallons would weigh 1668 lbs, wich is short of a ton by 400 lbs. But I want to know what will happen when you move it from point A to point B with 125 gallons of water in a 250 gallon tank? And exactly where underbody is there room for a 200 gallon fresh water tank and a 225 gallon waste water tank? Talk about a led sled. LOL

lol yeah, well we need the water to hose down the crowds that might horde our truck lol. We can reduce the water tank size, however we would just like to see from everybody's experience and knowledge what kind of weight capacity the step vans have. thanks for your help!

Also if you have any other possible solutions of procuring water for an ice tea/smoothie truck

whoaaaa

But your question doesn't make any sense. If your doing events you run a hose to your rig. If your in the same location every day (weather permitting) you build a small box and put a water tank in it and run a hose to your truck water pump. If you moving from location to location (different each day) you fill up a small on board water tank each night. I don't sell smoothies nor a lot of drinks for that mater but I go through 125 to175 gallons every two weeks and I have a water truck deliver it. And that water use includes using a pressure washer to wash my smokers and the drive. In order to find out what the legal limit is for your truck in your state you'd need to call your state police, or dept of transportation. Where do you live?

Aren't smoothies all ice? Are you making your ice on board? It takes several days to make ice properly for smoothies and shaved ice. At least that's what all the people on the shaved ice forum say. Although I have to admit most in that forum are elitist about shaved ice as if it were an art form.

Thanks for the great info! We will definitely check with local limits on water tanks, would you know by chance what weight capacity you have on your truck? or a weight capacity for a 25 foot step van? thx so much!

No I don't know or I would have said that right up front. In order to be legal you need to find out what the legal limit is for your truck in your state you'd need to call your state police, or dept of transportation. I'm not sure there is a limit, call fedx or a snap on dealer they may know.

Cool thanks!

There should be a manufacture's tag at the driver's door (?) giving to gross operating weight of the truck.  Deduct the empty truck weight to get the cargo weight capacity.    The weight listed by this tag, in many states determines the class driver license required to operate.  I believe 26,000 lbs & less does not require CDL license (?).

there are truck body builders in most towns or google truck body builders and weight capacities.
