REGO 12V 60A DC-DC Battery Charger

I previously installed a Renogy 40 amp DC-DC charger. It worked fine, but had limited settings and no Bluetooth. My new batteries want a low absorption charge set at 13.8 volts which the old Renogy can’t accommodate. Also I would like to have a reverse DC-DC charger to keep my Mercedes battery charged while parked. […]

Alpine Halo11 iLX-F511

I previously had replaced my junk Sprinter radio with a Pioneer Avic-W8400NEX. This worked out pretty well. It had wireless Apple Carplay and was pretty advanced at the time. That thing was damn expensive! After 4 years of use, I was *mostly* satisfied. But, since riding in Teslas I have grown fond of the oversized […]

Discover DLB-GC12-12V Lithium Blue 12V 200Ah Batteries

This will be my third Lithium upgrade in the same van. I’m unwilling to sacrifice any more space or weight, so I do upgrades as technology improves. First it was (2) Battleborn’s, then (3) Renogy. All performed fabulously (some Renogy hiccups were just rough software and resolved themselves after cell balancing), and met my expectations, […]

Equalizer Systems Emergency Operations

I regularly read posts about either being stuck with broken jacks or slides, or, people who travel without either for fear of being stranded. And I’m totally in that camp of not wanting the embarrassment and inconvenience of being stranded if possible. So I wanted to practice retracting my jacks manually. There are several excellent […]

Add Inside Remote Propane Switch

Ever since I upgraded to an Isotherm Compressor Refrigerator I have found my outside propane switch even more annoying. I get that its good to have an outside switch – in case of a leak or fire, but couldn’t LTV have also installed one inside also? Even when I had my absorption refrigerator, with hookups […]

Guide to Starlink For RVs in 15 minutes

June 24 2022 Update: Now that the RV plan came out I switched to RV so I could pause at times. So If you plan to use at home the convoluted instructions below are still correct, but for RV there is no service address and its a simpler signup. That said you may now have […]

Rewire RV with Xantrex 3000 XC Pro and (3) Renogy 100Ah 12V Bluetooth Batteries

Dec 2022 Update: The Renogys worked great after a few kinks were worked out and have been reliable. However I recently upgraded for more power to a pair of Discover Lithium 200 Batteries. The rest of this post is still relevant about installing the Xantrex, busbars, switch, etc. I only later updated the batteries themselves. […]

Deep Dive into Isotherm Cruise 165/219

Its been over a year since I installed the Isotherm Cruise 219 in my RV. I just completed a 3 week trip out west and I thought it would be a good time to record some thoughts. So here, in random order, is what I learned so far: Refrigerator Drainage I originally totally missed the […]

TST 507 Series 6 Flow Thru Sensor TPMS System with Color Display

Finally! TPMS. And no, you don’t need to install Borg stems! Here is the background: Many people buy DIY TPMS off the Internet, and have their stems crack on the way home or after a short trip. The reason is usually due to either a rubber valve stem, or more often, a dually valve stem […]

Replace RV Propane Regulator

My RV came with a propane regulator (Fairview) known for early failures, and sure enough, like clockwork, it failed before 2 years passed. The symptom was propane smell around the rear of the RV; but others report a reduced gas pressure as the first sign. Actually now that I think about it it may have […]

Adding a dash switch to IRD / Battery Relay

Many people who have switched to Lithium, particularly with more than 200 AH of capacity, have installed a DC-DC charger. But I am not quite ready. They steal some of the efficiency, have relatively low output, require a big chunk of mounting real estate near the battery, and its another item to break and ruin […]

Pepwave MAX Transit Duo Cat12

I previously installed a Cradlepoint IBR900 Router. I was reasonably satisfied with it. It wasn’t a perfect experience though. The registration process (required to manage remotely) was chaotic and took numerous calls and trouble tickets to be resolved. It immediately started crashing due to router bugs. Again, resolved through support tickets. It was a firmware […]

RV Dual Cigarette Lighter Socket and USB

This is one of those super trivial upgrades that I almost didn’t write up, except its really useful. My Unity CB had a dual USB socket behind the drivers seat. That was useful. My security cam stays plugged in there. But I really wanted a cigarette lighter plug there as well. I have a backup […]

Upgrade Battery Isolation Relay Cole Hersee

Just like clockwork, after about two years of ownership I noticed my alternator stopped charging my batteries reliably. Its always a little unreliable on my Lithium batteries. (I count on the solar to top them off.) But in this case the alternator completely stopped charging. (Although sometimes it would). From posts on the internet I […]

VanTop H610 10″ 2.5K Mirror Dash Cam

Update October 2022 – Looks like Vantop disappeared from Amazon. There are many there that appear to be the same manufacturer, but Wolfbox seems popular and well reviewed. See Amazon link at bottom of this article for Wolfbox. For my RV (and most others unless you have a really small van) the rear view mirror […]

Progressive Dynamics PD9180ALV

Note: This is an older post and I have subsequently upgraded to 300 AH of Renogy Lithium and a Xantrex 3000 XC Pro Inverter. Its like a domino. Each thing I kick in the RV causes some new deficiency to be noticed, that either wasn’t there before or had escaped my attention. After all my […]

Isotherm Cruise 219 RV Install

(Pictured on the left is the original Dometic refrigerator. On the right is my replacement.) Also see my postscript article where I summarize the experience once I got things ironed out! My RV came with an industry standard Dometic refrigerator. I won’t spend a lot of time on the deficiencies as they are well known. […]

SmartSolar MPPT 100/50 Charge Controller

Note: This is an older post and I have subsequently upgraded to 300 AH of Renogy Lithium and a Xantrex 3000 XC Pro Inverter. The solar charge controller still works great, I just moved it around! My new RV came with what I thought was pretty good solar. Only as I learned, it was just […]

Battleborn Lithium RV Install

Note: This is an older post and I have subsequently upgraded to 300 AH of Renogy Lithium and a Xantrex 3000 XC Pro Inverter. A few people have asked me why I didn’t simply purchase a third Battleborn. Answer is: No Bluetooth. This new technology lets you monitor the health of individual batteries – very […]

Magnum Energy ME-RC50 Remote Control

Note: This is an older post and I have subsequently upgraded to 300 AH of Renogy Lithium and a Xantrex 3000 XC Pro Inverter. So, I will be replacing my refrigerator with a compressor refrigerator (more on that soon). The first step in doing that is to expand the battery life by going Lithium (more […]

Pioneer AVIC-W8400NEX

DEC 2022 Update: The Pioneer worked pretty well but after 4 years I replaced with an Alpine Halo 11 iLXF511. This article is still relevant for some installation issues but the Alpine was much easier to install – basically plug-and-play since Critchfield offers a custom wiring harness. Times have changed I never used the DVD […]
