Probably a good idea. In my case, have 5200 watts of solar, if somehow that fails [I am running two strings on 2 solar controllers] I can use the Magnum to recharge the batteries, and if it fails, can use my 15 amp charger on my small generator. Redundancy is a good thing, especially here in hurricane country.

8v71's were a very popular engine in buses and trucks up until they failed to meet EPA standards and modern 6 cylinder 4 stroke engines replaced them. General Motors made several models of v design 2 stroke supercharged engine, 4/6/8/12v71's and its bigger brother, the 6/8v92. Had a couple of 8v71's in bus conversions, They can run 250 to 350 hp [turbocharged] Still a lot of them around the world, but if you are not a DIY kind of guy, you might have trouble finding someone to work on it. Most bus conversions in the US have converted to Allison auto transmissions.

Glen, like you, I have 3 packs, each limited to 20 amps by the BMS. If you look at a wiring size calculator, you will find even 8 gauge is overkill. Magnum is assuming one big battery, we are using 3. .http://wiresizecalculator.net/

I am running 8 gauge from each bank to inverter and it is well within specs.

Yes I am only pulling 48 amps out of batteries, so at full output, might get a little warmer.

Plywood. Unit is spaced about 1/2 inch off because of feet. No indication of any heat being transferred to the wood. Used IR gun on back of plywood and it is at ambient temp. Appears most of the heat produced comes out of the top grill. But I am inverting, know from other inverter/chargers, more heat is produced when unit is putting out a big charge. I don't use my unit for charging.

Just checked my 4448 with about a 240 volt 2500 watt load. Sides and front ambient temp. Top [big side with grill] running about 115 f. I have mine mounted on wall so all heat goes up through the grill. Ambient air temp about 88 f.

Lowes version. This is what I actually used, Unistrut is the actual inventor I think. .\ https://www.lowes.com/pd/Superstrut-1-5-8-in-x-13-16-in-Gold-Galvanized-Half-Slot-Channel-Strut/3128119?cm_mmc=shp-_-c-_-prd-_-elc-_-google-_-lia-_-206-_-conduitandfittings-_

You mean they loosen up and back out? I use lock washers, so as safe as any nut and bolt connection can be. Lots of nut and bolt connections on my coach.

Started using them on my first solar coach in 2007. Not sure what you mean by "fail from vibration". I do put a blog of silicon caulk on the the bolt thread so I have a visual reference when doing my monthly inspection. Probably 100000 miles total on unistrut, and no failures. Nice thing about unistrut, if you want to change out panels, no new or old holes to make or fill in, just loosen bolts, remove old panels , and install new ones, and retighten bolts. If I only need 8 ft, I mount 12 ft of unistrut, makes adding extra panels easy.

I use unistrut and fasten the panels to the unistrut with unistrut fittings. https://www.cesco.com/Unistrut-P1000T10PG-Unistrut-P1000T-10PG-Slotted-Channel-12-Gauge-10-ft-x-1-5-8-Inch-x-1-5-8-Inch-1-1-8-Inch-x-9-16-Inch-Slot-Size-Type-T-Slot-Steel-H

As Sehc said dc to dc charger, 12 volt alternator to 24 volts for battery. Do not know of any dc to dc step up transformer. https://www.solar-electric.com/victron-energy-orion-12-24-20a-dc-dc.html?gclid=Cj0KCQjwncT1BRDhARIsAOQF9LmTmqyzCUBm_fcERbmjaluHb3B_ZsSJJzUMxW0pitt3sgd1or6fZ-YaAm5

Yes he does, but for some reason, I think it was set up for 12s packs, so a lower voltage. Might be wrong though.

Thanks, just ordered one, turns out agm setting is 57.6, so close enough. Factory would have altered it to 57, but wanted to charge me shipping and $400 so I am happy with $299 shipped from batterystuff.com

So you called Schumacher and they built one to your specs.? How much and how many amps at 57 volts?

Another idea. https://www.ebay.com/itm/80MPH-130Km-h-85mm-GPS-Digital-Speedometer-Gauge-Odometer-for-Car-Truck-Marine/293203250483?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p205

Glen. I have been looking as well, trouble is the 14s 48 volt packs charge best at 56-57 volts, hard to find in a stand alone charger that will do that. Let me know if you find one. As John T mentioned, solar is the best way to top them off.

I don't pay much attention to the bars on the netgear. I have speedtest on my phone, and move the antenna to different positions, and test the speed with the app.

I have the Netgear 815, but it looks correct. They do not really lock in, they are just sort of a push in fit.

I have the MIMO, very directional but does improve the signal.

Maybe they have changed, but do have a friend that went from FMCA to Coachnet and got the $99 plan. Did you specify for your coach only? Their normal plans cover all your cars and towds. The $99 plan is, or was, for coach only.
