Unlimited showers if you have the water supply. They save propane as no waste from water storage.Our Atwood RV water does work well and does use engine coolant to heat the water while driving plus we have a "hot rod" to electrically heat the water if plugged in to shore power. But that's about it for advantages.Pierce Quote Selected

Re: Found a gv Reply #29 – March 05, 2017, 01:45:19 am John, unfortunately coach less at this time, as stated at the start of this post, still looking and researching. Owner is out of town till next week, so the 1000 mile round trip will have to wait a bit, and I am not legally qaulified to drive it my state. Was hopeing to take the written DL test and get a instructional permit and creep across the state line, and take the driving test, but the nearest DL office is 100 miles past the state line. State trooper would probably just issue a warning ticket, but insurance co would deny any claim. Ask the question if I could rent a 30 ft box uhaul truck and attempt to take the driving test and got the big NO as the GVRW was was less than 26,000. Jacking my own post kinda Quote Selected
Re: Found a gv Reply #30 – March 05, 2017, 08:26:58 am In Texas (and this is a good reason to go ahead and update your forum signature, no idea what state you're in), you also get a learners permit after passing written test so all you need is a licensed coach owning friend to ride with you to test.

Did you ever get past the head scratching phase of the project? Or did I remember incorrectly...DonDon,No, you remember correctly. With my back, I have put several projects on hold. The operation was a success (laminectomy) and I am a thousand times better now. So, I have the tankless heater and am trying to figure how to mount it so there is a foot above for the exhaust to draw and then make a 90 and out through the coach wall. I should probably go back to what my goals are. First, I would like to be able to warm the engine on cold mornings without starting the generator. We are usually dry camping so don't have shore power. Second, I don't like the noise the heaters make so I want to be able to remove the heaters and install heat exchangers in the original location. I have salvaged a couple hundred feet of copper pipe with thousands of aluminum fins so I will utilize them. Looking at the stock water heater I can see that engine coolant runs through it to heat the water while driving. I had the idea to put a small 12V pump that I purchased on ebay and direct the coolant back to the engine from the water heater and use it's internal heat exchanger in the opposite way. The pump is very small, works with hot water and can run all night without using much juice. For the tankless, I installed an aluminum bulkhead almost against the water tank in the water heater and water tank compartment so there is room to close the compartment door and clear the tankless heater. The coolant would then be sent to both the front and rear heat exchangers via the same type of small pump. 95% of the noise would be eliminated with only a low speed 12V fan to circulate the water. The problem so far is getting a foot above the tankless so it will meet the installation specs without going through the floor above and then making the 90 turn and out. I already used these heat exchangers without a fan to heat our house with a large diesel fired boiler located in the garage. It used over a gallon an hour and when the price of diesel went up, I removed the whole setup and installed a Toyo OM-22 direct vent diesel heater. A very excellent product. The Foretravel has much less insulation and single pane windows so it will need more than just convection to keep it comfortable. I have a unvented propane heater now to use for a backup. I even thought of just installing a OM-22 in the coach to use but I even though they are not that big, I can't find a convenient outside wall to vent through. They do have a fan but it's very quiet especially compared to the OEM heaters and use much less fuel. 90 % efficiency at 22K BTUs and High - 0.173 gal./hMed - 0.116 gal./hLow - 0.060 gal./hLots of choices here and I don't want to make a mistake. I took several months to figure out our solar installation and this is more complex than that.Pierce Quote Selected
Re: Found a gv Reply #32 – March 05, 2017, 10:58:08 am I think it would be easier and cheaper to go south to Mexico for the winter and go home when it warms back up! Thats what I'm hoping to be able to do one day. Quote Selected 2 Likes
Re: Found a gv Reply #33 – March 05, 2017, 11:08:23 am Stump,What can I say? Good food, clear water and a great climate. Our problem is not just winter but almost year around as most of the time we live in the Sierra foothills and usually camp up at summit elevations. June Lake Loop is about 8000 feet and cold at night. A combination of cold morning temps, high altitude, lower compression turbo engine and no heated screen like the Cummins have makes early morning starts difficult without some kind of block heater.Without my son's family living close in Sacramento, I would be down there full time.Pierce Quote Selected 2 Likes
Re: Found a gv Reply #34 – March 09, 2017, 12:00:24 am So is there a trick to raising the dash to get a look at the wiring, to see that's it not been butchered too much? Thanks coastprt for the pic of the ddec II connector. Weather & travel conditions and the owner on a business trip so far have interfered a journey to inspect the coach. But we have been communicating very well. So far so good, as has has sent pics of the good and known defects without asking, and has so far disclosed freely any known flaws as he has been living in it for a few months while his new house is being built. Price is negotiable based on what I see or detect. Any advice would be helpful. Brett is away at the Chandler fmca rally I believe. Quote Selected
Re: Found a gv Reply #35 – March 09, 2017, 12:58:45 am No trick on the dash grab front edge and lift it up there are clips across the front that hold it downYou might have to kind of work your way across. But it just flips up. Quote Selected 1 Likes

Re: Found a gv Reply #37 – March 09, 2017, 09:26:44 am And don't forget a 12" stick to hold the dash up. Don't use metal!! Too many things can be shorted if the metal falls into the wiring. Quote Selected

Re: Found a gv Reply #41 – March 15, 2017, 09:40:36 pm Man promised he would hold it for me, and would not take a deposit. He wanted to get a few things in order prior to my inspection and give me a call. Today his wife sold it. It was actually the 94 u300 SE listed on rvtrader in westcliffe, co., But I didn't want to post all of the facts on a forum. Kinda like the house we "bought" 2 years ago, full price offer and required a home inspection as required by the lender. Got the congratulations phone call.Offer accepted, earnest money accepted, I signed the contract and is was promptly delivered to the selling agent. A offer shot from the grassy knoll suddenly appeared the next day to the sellers agent same price, but specifically stated "no inspection required". A woman (and former attorney) was involved in that deal also as the sellers agent. Quote Selected
