1984 Suncrest 26'

So as I have posted before I picked up this beauty but still need more information on this unit. Please dont tell me to google it because I have tried and no success. The Motorhome came with the manuals but there is no information on size of the various tanks on this unit. Is there a way to figure it out? Are the tanks marked somewhere?

Mainly want to know the size of the fuel tanks yes it has two a Main and a Aux. The fuel gauge doesn't work so I can't tell when I'm getting low. I'm thinking the main tank is about 40 gallons and aux might be 25-30 gallons.

I assume when using the generator it uses the same fuel that the engine uses. I do know that the generator does shut off when it gets to the 1/4 tank left as we found out on the maiden voyage. We want to just switch the fuel to Aux when using the generator and just use the main for the Engine.

This might be common knowledge but the Engine is a 454 and it's on a P 30 chassis.

Thanks
Todd
  • google liquid capacity and it will list several sites that will calculate capacity based on dimensions
  • Measure the tank outside in inches, divide by 144 to get cubic feet, subtract 5% for wall thickness and multiply by 7.5 for gallons.

    If you need weight, multiply that by 6.5.
  • Thank you all for your tips I will crawl underneath to determine my tank sizes.
  • If you are willing to work a little, fill the tanks with fresh water and empty into a 5 gallon bucket, one @ a time, count the buckets and multiply by 5. This technique results in a real time/accurate solution, assuming you have separate termination valves.
  • At this time not really willing to do that much work:) This is currently just a Tailgating rig so if the info was there great. Being we only paid $2k split between 4 guys it's just pocket change. Been fun so far!

    GO HAWKS!
  • Todd, L x W x D = cubic feet then cubic feet x 7.47= gallons! Good Luck against Denver on Sunday!
  • Thanks I will do those measurements after I restock the RV for some urban camping in downtown Seattle.
