The only deductions from my bank by TSD have been for fuel purchases.

Well...there goes our customer service and Newmar quality. https://markets.businessinsider.com/news/stocks/winnebago-industries-to-buy-newmar-for-about-344-mln-quick-facts-1028526379?fbclid=iwar17kgtlkbwv2bg7rkuzka0jswsgo1fypxbnx_vcrn6jboiujmqrbnshgww

If anyone is interested in purchasing a water softener for your coach, this is a good time. I ordered the On The Go OTG4-DBLSOFT-Portable 16,000 Grain RV Water Softener from Camping World. Using the coupon code "endofsummer" and free shipping, I paid $212.32 + sales tax. Amazon had the best price I could find $279.90 + tax. I'm not endorsing any product.

Rich, when I had the issue I disconnected the chassis ground cable to kill the engine.

Glad to hear, Lyle; more evidence its not an inherent problem like a so-called tech told another Newmar owner.

My gut tells me it has something to do with the electric/electronics wiring controlling the fuel shut off valve.

I had the same issue on a 2008 Freightliner with a Cummins engine. It happened twice within a matter of days and never happened again. At that time, Pat was still at the Gaffney Service Center, I called her to see if they had any information on the issue. It just so happened they had a motorhome in that had been there for 3 weeks as I recall. They started and shut it down 8-10 times a day and never duplicated the problem. As far as I know they never did diagnose the cause the problem. For me, it happened those two times and never happened again the last 4 years I owned it but you can bet I thought about it every time I turned the key off.

I used diesel to start brush fires for years when I had my ranch. I would use a paper feed sack to start it. The crews clearing land for highway R-O-W's used diesel to for years to start the fires; I don't know what the use today. Maybe we have a more volatile diesel here in Texas, Joe. Just to not stray from the topic, I don't recommend burning the diesel while its in your tank to destroy the algae.

As long as my exhaust smells like french fries, I don't care.

My suggestion would be to call them and ask. I haven't heard any gasser comment on fuel cost/savings on any of the forums I visit.

The TSD Logistics program is for diesel fuel only.

This is an interesting topic. So we go from fossil diesel to biodiesel and now possibly to renewable diesel. https://www.chron.com/business/energy/article/Valero-Darling-planning-major-renewable-diesel-14424412.php

It is not an inherent problem for DSDP's or VTDP's. Maybe this link will help. http://www.irv2.com/forums/f103/getting-hot-under-kitchen-sink-from-oasis-439468.html http://www.irv2.com/forums/f103/excessive-heat-kitchen-area-under-sink-427563.html
