  1. Getting ready to install 400 watt Renogy solar panels with 40 amp MPPT controller to our 2007 Endeavor. RV is equipped with factory 8kw Onan Generator with 2000 watt Magnum inverter.  Do not plan to change any of that. I have reviewed several wiring diagrams and YouTube videos of proper set up but none address how to deal with potential isolation of solar system from batteries while on shore power or while using generator. Do I need to add a cut off switch to the lead from the solar to the batteries to isolate solar system when on shore power or when running gen set. Renogy has not been too helpful with set up of this nature.  Plan is to use solar for battery charging when dry camping in National parks or when restrictions to gen set run times are in place. I am sure someone has dealt with this before. 

  2. Thanks for responses. Yes, I know batteries were on borrowed time but had one more trip scheduled before putting coach to bed for winter and was planning to replace next spring. Crown 260's are on order. Generator is 8 kw and has held up running both AC's and MW at same time in the past. New refrig is Samsung and says 5 amp draw max. I was only running ac's when on shore power anyway,  so not sure that was an issue. Will see what happens when new batteries arrive. 

  3. Magnum inverter/charger in our 2007 HR recently started shutting down giving us "internal fault 1" code while on generator. I powered down, did a hard reset and all seemed fine for while but next day and again day after, had similar issues but reset cleared code and all was fine. Batteries (flooded Crown 235 amp hrs) are approaching 8 years but holding charge overnight even running a recently installed residential refrigerator. Got home and everything seemed to be fine while on shore power for next few weeks. Hit road again and has similar issues while on generator but figured once I got to full hook up, 50 amp service, everything would be OK. Not the case, now fault occurs withing 5 mins of powering up either on generator or shore power. Reset clears fault but not nor long. Powered everything down now. I did observe that one of the batteries appears a bit swollen but water level was fine. Curiously, the AC unit continues to run even after the inverter cuts out. Apparently the AC units are bypassed and directly feed by shore or generator? unfortunately Refrigerator is not but I am guessing that is because of my choice of which plug I used when powering frig when i switched from the old gas/elect. Could not find fault codes for Magnum. 

    So, does it sound like inverter is the issues or perhaps is a dead or shorted battery is causing the fault?  

  4. Will be headed East out of Vancouver in July along TCH and looking for suggestions on Campgrounds in the Lake Louise area or west to Kamloops area. Traveling in 40ft with toad, Electric preferred but no essential. Any suggestions on central location for best scenery, possible on lake. 

  5. I have encountered no issues with burning furnace while traveling. If temps permit, i will instead run Gen Set and roof unit on Heat Pump mode and kept coach toasty. Ambient (outside) temp needs to be 38 or so but still plenty of times this is the case and dash unit just not enough. 

  6. read some time ago about using Ridex periodically to clean black tank but can't seem to find  thread on forum. even after using water flush system seem to have debris on sensor getting a false reading even when I am sure the tank is empty. Any thoughts or comments on benefit of filling a clean tank with water and dumping recommended amount of Ridex in tank and driving around for a while then letting is sit for few days before dumping and flushing tank. 

  7. Nansue 58, If it works ok on electric but not on propane, and it has not been on propane in a while, may be that propane bleed off and there is air in the line. if so, igniter will attempt to light up to 3 times, and if no flame present, lock out. Try purging the line by turning on closest gas appliance, then turn fridge off, then on again to restart sequence. Listen outside to see if you can hear the igniter spark, then the flame. may still take a time or two. Remember that the fan will run and sound like fridge is working even if flame is not on. 


  8. Monument Valley (Goulding) at least 2 days and Zion ( Watchman) for 4 days are must stays. Bryce canyon a must see. Two days if hiking thru formations but can make a day trip from Zion if time is tight. Regret not making it to Arches.

    Great trip in 2016

  9. Agree with all said above. Don't know if "source" of heat is microwave or electric element but keep in mind that when on convection, you may use metal rack or pans, so perhaps not microwave. We use ours both ways, frequently in the course of the same meal. will bake in convection, then take out food and rack, then use the microwave to cook something else being careful to remember that the interior surface and the rack is still hot, unlike a mw only oven. we have baked cakes, pies, bread, pizza, scalloped potatoes, oven roasted veggies all using convection. 

  10. Zion for sure. Watchman Campground at western entrance is one of the few national park cg's that has electric hook up(30A)

    From there you can do day trip to Bryce or spend several days there.

    Depending on size of your Rig, might want to avoid the tunnel in between.

    Arches another good stop.

    Also look to get over to Monument Valley in the southeastern corner of UT. Goulding Campground a good possibility.

  11. DW and I are planning a west cost trip in late summer 2018 and planning to spend a few days in Yosemite. We love staying in national park campgrounds and have stayed in numerous where the posted length is 35' with our 40' unit and the toad and still kept all tires on the pavement. Yes, that included Mather in Grand Canyon. I see several sites in Lower Pines CG that are 35' range but the big question is maneuvering thru the campground as well as obstacles on a particular site. Also depends if park refuses to allow larger units. Has anyone with 40 footer had any experience there or have suggestions for private options not so far out of park that don't seem like parking lots? Additionally, does non weekend in September tend to be less crowded or is it about the same regardless?   

  12. Close is relative term but might check Foxfire in Milton WV, approx 40 miles west of town. It is KOA. Avoid Kanawha State forest, not big rig friendly. St Albans Roadside Park, approx 15 miles west of Charleston has a few sites but limited services. (115v power and dump station but is on the river, Not so sure about Staats Mill in Ripley. pretty much middle of nothing.


  13. Great looking installation! May have to reconsider future change out myself. So far, our Dometic works reasonably well, but not without issues.  We do a fair amount of boondocking so draw on battery banks and need for running genset is a concern, particularly when at a National Park site with limitations on hours of generator operation. How much of an impact might that be, if for example you topped off battery charge at 10:00 am and run minimal lighting and normal parasitic loads during the day and can not use gen set till 5:00 or worse case, topped off at 8:00 pm and cannot recharge till 8:00 morning. Presently i can do the later, watch an hour of tv, even run furnace on a chilly night and still have 12.2v in the morning. Any thoughts?

  14. Glad to have the clarification. While I too suspected that this was the case, I have always unplugged or tripped disconnect just to be on safe side.

    Like Brett, seemed to be best practice and eliminated potential for something not working as it should.
