    Setting up Flippac camper

    Regards to thin wall tubing. Try standing on a beer can. Or flick the wall of a bicycle frame. You don't need it to be thick to hold the weight. It needs to be thick enough not to dent. A dent in a tube is it's Achilles heel.

    Colorado Gets Tough

    The Boulder Ranger District has long been an enforcement nightmare. https://www.5280.com/2018/01/danger-in-the-forest/ I wish the other Ranger Districts would be more proactive about enforcing the 14-day rule. Not just for grow operations like above Nederland but to prevent people from...

    Battery isolation ideas

    Just to put numbers to one for example, a typical Bosch p/n 0332019150 40A automotive type has a pull-in voltage of ≤ 8 V and a drop out of 1 to 5 volts. So the indeterminate region is at least 5 to 8 volts where you can't say what it'll do. Might pick one, might chatter. It depends on...

    2012 Toyota Tacoma TRD 4X4 Extended Cab - $29,000

    The price is there, just looks like it needs a return after the line to flow into the first photo better.

    2006 Toyota Tacoma 4X4 with FlipPac 16k

    It looks like a TRD Offroad, so SR5 4.0L V6 and 6 speed stick shift.

    Learning to weld questions

    I'll never understand not wearing appropriate shoes. Although I do run Chacos in daily errand use so I'm not really a good role model but at least I go with proper boots to work, 'wheel and hike.

    Learning to weld questions

    Wearing a respirator is also a good idea. The 3M 2097 (P100 with nuisance organic vapor) filter is what I use, it's a pancake filter intended for welding and fits pretty well under a hood. Everyone probably knows about galvanized but you really are sucking in some bad stuff even with plain...

    Learning to weld questions

    It's not a secret trick, grounding the positive (this is called DCEN, meaning DC electrode negative, the ground clamp is positive) is correct for flux core wire and with some rods (sticks). This is considered straight polarity. Normally with solid core, gas shield MIG you use grounded negative...

    HAM radio/amateur radio FAQ

    Yup. There's a daily morning net here called the Oatmeal Net and it's literally a 10 second check-in with your call sign and what you had for breakfast. Taken out of context it's silly but what it amounts to is 20+ long time friends checking up each other every morning. Gen Z would do it with...

    HAM radio/amateur radio FAQ

    Yup, get them installed and don't be afraid to use them. It may not always be riveting topics but just keying up and saying good morning to the regulars on a local repeater during your commute is significant. You know your radio works and get to know other hams around you.

    HAM radio/amateur radio FAQ

    The questions you're asking @pith helmet are core to ham radio but can be complex to answer because the scope and scale vary with the emergency. It could be as simple as your radios are an alternative to cell phones and range all the way up to a nation-level coordinated net of amateurs. I...

    Orux can also read Mapforge and Garmin IMG maps, which is pretty handy.

    HAM radio/amateur radio FAQ

    And it's not just on 40m they're doing it. Intentional interference is something the repeater operators here in Colorado (I think NM, too) have been dealing with lately on the linked systems (Colorado Connection, Skyhub Link, Rocky Mountain Ham DMR). Just don't get it. We just lost our 3.5...

    2 spare tires?

    Got it, bad Overlander®. So am I to wait for road side assistance? Never thought my life would be in peril walking a couple of miles to find 4 bars of cell signal. But then again I forget, we're thinking about being stuck in Botswana with a sat phone at hand not about driving trails in...

    Will this radio transmit on GMRS frequencies?

    This statement is 180° wrong. Actual USAF and Army MARS/CAP cares about the equipment you use far more than the FCC. They require operators to have radios that meet NTIA standards, which for the most part ham radios do not. Even old used public service and business band radios are marginal...

    HAM radio/amateur radio FAQ

    There's a lot made of iMessage or Signal. Now that's encrypted messaging. I wonder what these guys think of spread spectrum, something the FCC asked hams to take beyond the miliary and experiment with 40 years ago. Or PC-ALE, the automatic link establishment on HF that frequency hops to find...

    HAM radio/amateur radio FAQ

    https://spectrum.ieee.org/tech-talk/telecom/wireless/is-ham-radio-a-hobby-a-utilityor-both-a-battle-over-spectrum-heats-up It's not just Winlink they don't like, it's anything they can't tune up and listen to with a boat anchor. It seems to me to boil down to not liking people experimenting or...

    2 spare tires?

    I've had more than one flat on a trip but my $0.02 is two spares are important when walking to get or summoning help is not possible. In my case I was able to plug the second flat and limp to a tire store. Inconvenient, yup. Life threatening. Nope. This was before the proliferation of cell...

    Ford Explorer Timberline

    It could be worse, Toyota decided to put a typical 1st gear and only one OD in my 6 speed Tacoma. If they had two overdrive gears then I could at least drop the axle gearing to compensate. The transmission is the same as the Camaro and some Cadillac, which, you know, makes perfect sense.
