    Kenwood TM-261A (2m mobile) installed

    Thought I'd do a quick writeup of my Kenwood 2m mobile install. The TM-261A is a fairly old radio and this one I got off of Craigslist I think about 10 years ago for $25. The radio itself seems to work except for the keypad on the mike. This is sort of a "training radio" for me. I'll likely...

    Safe way to mount fire extinguisher in cab?

    Back in October while on a trailer camping trip, the wife and I came across a terrible car accident on the Navajo reservation. Single car, rolled over multiple times with 2 ejected and one pinned under the car. We were able to render assistance until the paramedics and police arrived but in...

    Goodyear Wrangler Ultra-Terrain AT - is this a new tire?

    Getting close to needing new tires, the Goodyear Wrangler Kevlars seem to really suck bad in snow and ice. Shopping in Discount tire my "go to" has been the Falken Wildpeak AT3W. But then I saw this Goodyear Wrangler Ultra Terrain AT. Seems to fit in the GY lineup somewhere between the...

    Mobile Radio choice: Dual band vs. 2m?

    (First off, sorry about blowing up this sub-section with questions, but after a rather eye opening experience, I've decided to upgrade my communications ability in my F-150.) I'm starting to realize my $25 purchased-off-CL-a-decade-ago used Kenwood TM-261A may not be the ideal radio for my...

    Microphone dilemma, Kenwood TM-261A

    Probably nine years ago or more ago I got my hands on a Kenwood TM-261A mobile 2m radio. I got it cheap off of CL and the seller told me the keypad on the mike didn't work (it came with the MC-53DM mike with the numeric keypad.) I should point out that these microphones use an RJ-45...

    Antenna options for aluminum bodied F-150

    Thanks to coming across a terrible car accident in the middle of the Navajo reservation in AZ (where 911 doesn't work - how many of you know that?), I've decided to upgrade the comms capability in our camping tow vehicle, a 2018 F-150. I have a couple of radios already, a Yaesu FT-50 HT and...

    Charging E-bikes from a 12v source - math check?

    So I admit it, math and science were never my strong subjects in school. My undergrad major was history and I literally took the least amount of math and science I had to in order to graduate. :D Anyway, we have E-bikes now and I'm curious about keeping them charged up on the road. On a...

    12v Fridges going "Mainstream?"

    Like many of us, I'm sure, I do a lot of my shopping on Amazon. Lately I've been seeing a lot of bargain priced 12v fridges like this one: https://www.amazon.com/Kalamera-Portable-Refrigerator-Electric-Traveling/dp/B0899XY978/ref=pd_ybh_a_3?_encoding=UTF8&psc=1&refRID=36513GZ9JBGYTT6R9T0D...

    1 year report on my new-to-me 2018 F-150 3.5 EB....

    Yup it was exactly 1 year ago yesterday (8/24/19) that I flew from Denver to Salt Lake City, was picked up at the SLC airport by the folks at Kentson Car Company who then drove me to their dealership in American Fork (near Provo) to pick up this 2018 F-150: This photo was taken in a parking...

    "Solar Generator"

    I know I'm not the only one here who is a little bit annoyed by this term that seems to have cropped up for the plethora of portable power packs out there. :rolleyes: Nevertheless, there certainly seem to be a lot of them out there. Look at what shows up on my Amazon feed: I'm assuming...

    "Simple but it works" 12v Power box writeup...

    This is really a companion to my other thread where I installed a Renogy 20A DC-DC battery charger in my 2018 F-150. https://www.expeditionportal.com/forum/threads/installing-renogy-dc-dc-charger-in-2018-f-150.214386/ That thread focused on the Renogy charger and how I got it installed and...

    Aftermarket seat options? Do they even exist anymore?

    Are there any companies that make aftermarket seats? I love everything about my 2018 F-150 - except the driver's seat is killing my sciatic nerve on any trip longer than about 30 minutes. This is basically from about my right butt cheek all the way down to my right knee. Weird thing is I...

    Constant voltage/float voltage for 12v FLA settings?

    Trying to set up my Renogy DC-DC charger and I wanted to tap into the group wisdom here for the settings on the DIP switches. Looks like the Renogy can do 3 different Constant Voltage/Switchover voltage settings: 14.4, 14.1 and 14.7, and 3 Float voltage settings, 13.8, 13.5 and 13.2. These...

    Installing Renogy DC-DC charger in 2018 F-150

    Posting this for anyone who might be interested in doing something similar. Background: The idea behind this came from my previous vehicle, a 2004 Suburban. When we camp we use an Indel-B TB 41 refrigerator and in the past we've had "issues" with it discharging the battery enough to cause...

    Ratchet straps, electrical cords and other "tangle-ables"

    How do folks here store their ratchets straps, ropes, electrical cords or other things that are liable to get tangled up when stored? What "hacks" or tricks have you found to keep such items both quickly usable but also not get them tangled up? I carry several ratchet straps for tying down...

    Some minor "mods": Builtright Industries interior and seat covers...

    So here's what I did on my first not-quite-quarantine-but-highly-recommended-to-stay-home Saturday: Thanks to another member here, I 'discovered' Builtright Industries which seems to be a small company making accessories for Jeeps and Ford F-series trucks from about 2009 to present...

    Is it stupid or will it work? Charging aux battery through 400W inverter?

    An old saying I heard in the Army was "If it's stupid but it works, it isn't stupid." So I'm tapping into the collective wisdom here to see if this idea is stupid or if it will likely work. First off, I originally posted this a couple months back as a response to this thread, because what...

    E-bikes?

    Does anybody here use an e-bike? Wife and I are thinking of getting a couple to add to our trailer for our summer camping trips. There are many places we go that have bicycle friendly roads and trails. We have regular bikes now but don't use them as often as we'd like, likely because we are...

    Anyone care to comment? Used LiFePo 12v batteries from medical equipment?

    A woman in our camping group sent this link to me: 138 AH from such a small package is appealing. The 'story' I heard is that the various safety rules regarding medical equipment require medical providers to dump these batteries when they still have 80% of their useful life so there are...

    Super-simple 12v power source for fridge?

    As I posted here: https://www.expeditionportal.com/forum/threads/outfitting-the-new-to-me-2018-f-150-ecoboost-specific-thoughts.208642/ I have a new truck. The Suburban is currently being used by our daughter-in-law until they can replace her old Traverse that died a couple of weeks ago. In...
