  1. I replaced my MacBook Air yesterday with a PC lapotop......Love it and but over $1000 in the bank!
  2. Totally agree on Marine Grade cable. Use nothing but tinned MG cable on my boat that lives in salt water. But on the truck and camper, all the other factory wire is simple copper. My last truck was 13 years old and 225,000 miles, up here in salted road New England, and all the auxiliary wring I installed for winch, truck camper, etc was fine. If you use good wire routing and proper glue filled, shrink wrap, protected connections....you will be good to go with quality welding cable.
  3. I hear ya! I'm ordering up 60' of 2AWG welding cable, solid copper. USA Made.....Will fuse it at the trucks battery with a 50amp Circuit Breaker and at the input to the trailers batteries with the same 50amp circuit breaker With a 40a charger, do these numbers sound right?
  4. Thanks! Good Advise..... My friend who is a head engineer at Disney World would get a kick out of your last statement.....Love it!
  5. Towing, I'm usually at 2200-2500 RPM.....Not towing it is around 1800 RPM I only need this extra battery charge when towing.
  6. Here's the deal......I need to run a 2AWG wire from the front of my pickup to my travel trailer for a DC to DC charger I have a number of spools of 10g THHN wire from many past electrical jobs I believe 6 #10 wies equals a #2AWG Is it advisable to make up cables like this to run 30'. I could twist all 6 wires together and then use plastic conduit to cover Thanks!
  7. Thanks John, The dual battery systems of which I think you are referring, are a simple high current, continuous duty relay that is activated only when the truck is running and simply switches between the trucks battery and the aux battery. Or a simple set of large diodes in the more vintage devices. Many modern vehicles ( since about 2006), might have a “ smart” alternator and these relay type systems or diode based systems will not work properly. My 2018 Ram has a VERY smart alternator and therefore I’m forced to use a much more sophisticated Dc to Dc Charger that I sourced through Renogy. My understanding is that these DC to DC devices do incorporate some type of advanced charge profile. The reviews from the road have been extremely positive. We shall see when I head Southwest in a January.
  8. Thank You!....I'm going to use anderson connectors as I'm very familiar with them. Being able to charge both trailer batteries and the aux battery from the trucks 220A alternator would be a huge win!
  9. Here's the deal..... I have a Ram pickup as my tow vehicle. In the bed of the PU I have a 100Ah AGM battery to power a portable refrigerator , a winch and other electrical demands when away boondock tent camping from the travel trailer. This battery is charged with a 120w portable panel and a 40a Renogy DC to DC alternator powered charger while the trucks engine is running In the travel trailer I have two 110Ah AGM batteries charged by 420w solar on the roof. Is there a way I can safely, without damaging the batteries, connect the trucks aux battery to my trailers system to increase 12v electricity storage. The trucks battery is not the same age, make and model as the two batteries in the trailer. I've searched this and am not finding any device that would accomplish this. Thanks
  10. Your best solution is a DC to DC charger. These used to be huge $$ but Renogy recently introduced one that would be perfect for charging a toad at $129. They make two units currently. A 20AMP and a 40AMP. The 20AMP would be all you need. Do a YouTube search on the Renogy DC to DC Charger. Great product at an affordable price and no mickey mouse relays or screwing up your main engine battery. And....Many modern vehicles have the alternator controlled by the computer. They can be damaged with a simple relay solution and you certainly don't want to just parallel the toads battery.
  11. More info: https://www.cordcuttersnews.com/t-mobile-now-offers-home-internet-for-50-a-month-with-no-data-cap/ I'm on waiting list now.....The new 600mHz and 5G is a huge game changer.....Hurry up T-Mobile and Elon Musk!
  12. The advantage of ATT-TV is if you have an ATT hotspot, there is no hit on your data. So a simple Mobley and ATT-TV and you can stream all you want for about $70 a month. I also have T-Mobile hotspot that also allows unlimited streaming of ATT-TV for when I can't get a good signal grom ATT...But recently in the past year or so this hasn't been an issue. ATT has worked everywhere I traveled. I hate to give up the T-Mobile hotspot because I'm a beta user and it only costs me $23 a month I also have Unlimited data on Verizon phone but only 15G is I use it as a hot spot. Streaming is still the future....but it has some serious growing pains.... Oh...and I tried YouTube-TV for a couple months. Didn't have the channels I wanted that ATT-TV had. Worked fine though.....Currently I unsubscribed from all streaming channels except ATT-TV and Amazon Prime Video
  13. Noticed the same thing.....But you have to check them out because sometimes they are true! I've been wanting to buy a Rooftop Tent for my truck for some time. Here in New England they are very rare and not ever offer for sale used. Last week I was ready to order a Smittybilt RTT from a vendor. Total with shipping and tax was $1100 At 4am on Monday morning I opened Craigslist like I do every morning when I'm looking for something. Punched in Rooftop Tent and an add came up for the exact tent I was looking for, used one weekend, and mounted to a Lowes $500 trailer.......Selling all for $800! I thought it was a scam. I sent an email through Craigslist and got an almost immediate reply. Drove the one hour each way and bought it. Trailer and tent are practically brand new! Sometimes it is too good to believe......But it is!
  14. I recently answered another post where a reader was asking about simple, inexpensive solar. I responded and thought maybe it would be helpful over here: Athough this system is being used in a Rooftop Tent, it would be applicable to any small travel trailer or camper...I recently bought a small system to be used with my new Rooftop Tent.My existing toy hauler trailer has all top shelf equipment.http://rvbprecision.com/rv-projects/solar-install-grey-wolf-19rr-toy-hauler.htmlBut I didn't want to spend that much on the RTT system. A whole bunch of research and here is what I bought:ECO Worthy 120W 12V foldable panels (Ebay $150) These will be used in portable deploy to take full advantage of the sun locationECO Worthy 10w X 2 solar panels (Amazon $21 each) These will be permanently mounted on the camper cap on the truck to maintain the batteryPowMr 40A Charge Controller (Amazon $20) See my article on portable solar on my web page about this unit ... www.rvbprecision.comWeize 12V 100AH AGM Deep Cycle battery (Amazon $160)AiLi Battery Monitor (Amazon $43) Great reviews and tells me absolutely everything I need to know about the system8Ga Welding Cables, 25' Red/25'Black (Amazon $42)Misc connectors, fuses etc ($20)Total $477The plan is a battery box containing all the distribution, battery and controllers. Easily secured in the truck for long term use and removable for winter storage and/or other use.I do not want to tie into the trucks electrical system as I'm concerned about tapping off the alternator causing issues with the computer. (2018 Ram 2500 6.4L gas)Simple buss panel in the RTT for lights, USB charging, fan etc...connected by one 10g connecting cable with quick disconnect to the portable battery box.I have been using the ECO portable panels and the PowMr solar controller in the Toy Hauler. The ECO Worth panels were a gamble, but they have been working great as additional solar gain to the 420w I have on the roof. A few friends have also bought the same panels and are very pleased with performance. http://rvbprecision.com/rv-projects/adding-more-solar-to-existing-system-portable-panels.htmlThe Weize battery is also a gamble. But it was the least expensive, AGM / 100AH battery I could find. In my trailer I have two Group 31 AGM Duracell batteries. Sourced from Sam's Club over 5 years ago. The trailer has over 50,000 miles and I spend three months a year in NM/AZ and just about every other weekend at various events. I've turned the generators on four times in 5 years. Only for AC and wife's hair dryer. 2000w Inverter, for Coffee(Keurig) and Toast, 12V for Computers, TV(2) , cell boosters, etc are going all the time. Batteries have never been below 70%....Still going strong. At the time of purchase they were $160 each. Smok'n deal!Hope this helps!
  15. Here is a quick write up on my installed aux solar panel www.rvbprecision.com
