What are the limits on how much bio you can carry. I have a couple cross country trips planned and the monre I can stay away from the diesel pumps the more $ in my pocket. Also anybody in either AZ/FL making bio? Heard sometimes the best way is to get into a bio club in your area to get cheap bio.

I dont know what the limit is.. Id guess if the containers are DOT approved the only limit is your GVWR.
You could put a couple 100gal tanks in the bed and be legal I -think-.
I dont think they can say anything if they dipped the tanks.. I mean who keeps receipts? I know Ive bought bio and not even thought about that.
Just be careful (obviously) of the extra weight and the changes in handling and braking.
As far as bio co-ops and stuff, Ive never found one with prices that were much less than pump diesel. plus you need to worry about road taxes and fuel quality. I just buy from a station when Im feeling guilty about the smoke I gave the last tailgater

I already have a 100 gal semi tank in the bed. In theory I could 2 more for 300 gal total but then I cant tow anything due to the weight. However I think 1 more would work. (2) tanks 200 @ 7lbs/gal 1400 in the bed. with a range of about 3000 miles @ 15mpg

3 tanks 2100lbs in the bed, 4500mile range.

Actually my truck is 2600 empty on the rear. I could do 3 tanks and ~ have about 2k for hitch weight.

I may be wrong but if you have over 300 gallons you would have to comply with DOT regs, like stopping at all RR crossing and also place signs on your truck just like fuel tankers do.

even with bio? I dunno either.

You can have 1000# of combustible fuel w/o jumping through all the hoops. This equates to just about 140 gallons which is a 105 gallon L-shaped tank in the bed plus a 35 gallon tank on the truck. Funny how the math works. It's the same set-up I picked after discussing it with the state patrol folks. I can go well over 2500 miles before needing fuel. hope this helps, cd

2500cdt,

I did a trip back in May. Fl to Wa. and back. I hauled 375 gal with me, and a full tank. my truck had a little squat going. but it beat paying the pump. I had no problems, well except the tranfer pump dieing on me. I leave next friday to go to Nevada in My 1st gen. I will have 3 50 gal drums and a barrel pump for the trip. Good luck.

Bob.

Bio diesel is not looked at [ by those that know what there talking about / authorities try to enforce a lot of what they believe ] .
I have seen some similar questions about bio , garage storage ect. , and those officials that have bothered to really look at bio , in many states , have figured out that there are no hazards to bio , spilling ect.
Out of sight out of mind , keep the tanks covered , do not advertise [ bumper sticker .

If that was the case of anything over 140 gallons of fuel then many semi trucks on the road today would have to comply with the same DOT rules as fuel tankers do and that is not the case. Did you know that many semi trucks on the road today have twin 100+ gallon fuel tanks and they don't have to comply with DOT fuel tanker rules.

2500ctd,

I am an RV trailer transport driver, and had the same questions, local shops here in Goshen, Indiana where my main terminal is located say that 119 gal auxillary fuel tank is the biggest you can carry.

I posed this question to a well known Texas state trooper who gives legal advice on Sirius satellite radio. His answer was that if my tank was set up as a "transfer tank", meaning I had to get out and fill my OEM tank from the auxillary, like pumping from a station pump, then yes, 119 gal is the limit (size of the OEM tank does not matter, the limit is on the aux tank only).

However if the tank is plumbed directly into my truck's fuel system so that I did not have to leave the drivers seat to start or stop fuel flow from it, then I could have as big of a tank as I wanted as long as the fully fueled weight did not exceed my truck's GVWR, and it was made by a DOT licensed tank manufacturer, and made to DOT specs for impact strength, baffling, etc.

90dodge,

What in the heck kind of tank were you using that you could take 375 gal with you?
