RE: Solar Install
Here's one. Narrowly escaped.
There's another where 3 people were killed as a result of swerving to avoid flying panels. Any of the solar forums, you find at least a few people stories of avoiding flying panels.
The point is...don't do it.

DOT or NHTSA will have the statistics you're looking for.

RE: Solar Install
So you're one those guys who slaps or should I say "sticks" with tape, panels on a roof and calls it good? Mine aren't going anywhere. Yes, use what you want to your own and others detriment.
How's it gonna feel when unbeknownst to you, your "right" tape job begins to rightfully work itself loose and panels end up through the windshield of a minivan full of kids or worse, causing multiple vehicles to crash? It happens more often than you're willing to admit, obviously.
There IS only one way to install panels--the safe and secure way. We're not talking about plastic moulding or fiberglass body trim.

RE: Solar Install
**Do Not** use ANY kind of tape as a primary fastening device on a rubber roof to secure rigid framed panels.
As mentioned, find studs to drill into. Look at using aluminum Unistrut as a base or frame. Your panel dimensions will not land exactly where the cross members are. A little pricy, but its WAY lighter than the steel version. It's easier to cut and work with and wont look ugly in a few years. I suppose you could even hit it with a coat of white paint to cut down on the little, extra heat absorption. Your choice.
I just added a three more panels to my array using the 2" tall version (only size available) Unistrut, self drilling (not self-tapping) stainless lag bolts, fender washers, 1.5" wide Eterna-Bond tape and Dicor lap sealant. We know Dicor is perfectly compatible with TPO and EPDM. Other sealants...mmm...maybe not. Plus, it's far more pliable to remove or to clean and reapply. Urethanes, like Sika are a little too good at adhering. I don't need that on the roof.
Properly clean and prep all surfaces (denatured alcohol, mineral spirits or sparing use of acetone and Scotch Brite pads work well).
Using a total of six 5/16" x 1.25" bolts, 1/4" pre-drilling all holes was necessary.
Next, cut roughly a 3" long x 1" Eterna-Bond tape and apply over all pre-drilled holes, noting location of hole. Be sure to press down hard across the entire strip of EB. Its pressure activated. Repeat these steps at all penetration points.
Next, Add a large dollop of Dicor onto EB tape.
Center and align corresponding Unistrut slot opening over noted pre-drilled holes. Press down. Allow Dicor to evenly compress and ooze out from under Unistrut.
Install fender washer on bolts. Preferably, using some kind of impact driver, locate hole with point of bolt and drive it in with moderate pressure. It'll just spin otherwise. Stop at about 3/4 way in and use a ratchet to finish by hand tightening. Note: Over tightening or using impact to fully drive bolt may result in stripping. Now, you have to start over. Don't do that.
Once all bolts are installed, apply Dicor to fully cover bolt heads and washers. Done.
Arrange and install panels using Unistrut cone-nut washers or whatever bracket fastening system you choose. The idea is to plan for expansion and only drill holes once. MUCH easier.
Anyone can drill holes, destroy their roof and randomly throw up a bunch of panels.
Somewhat related tip:
You may already know it, but try not to walk on your roof with shoes. I'd rather ruin a few pair of socks than forget to check and track a tiny rock or two. Or in my case, a metal shaving that burrowed itself into my shoe bottom then transferred into the rubber roof. So much so that I felt it might become a water intrusion point, so I put a piece of EB tape over it.
Good luck

RE: We knew it was coming...
All I know is we were well on our way to energy independence with the pipeline scheduled to come online within a few years in early 2020, prior to the absolute insanity that took place.
I'm supposed to believe those same people who created this mess? No thanks.
Whoever voted for the current guy and his party, owes me gas money.

RE: New Superduty gas engine for 2023.
Its interesting that all the offerings are push-rod motors. Superduty customers have been wanting more than one option for years now.
From '99 all the way to 2020, the only push-rod motor option was the Powerstroke.

RE: How to remove omnidirectional antenna
Didn't want to have to remove the metal post. It isn't really necessary to fit the panel, but I think I will remove it now. I'll have that much more room.
I just figured the less I have to deal with, the better.
Thanks

How to remove omnidirectional antenna
Trying to make room for a solar panel. Don't really want to break it off since I'm sure there is a way to remove the plastic dish from the metal post. Any help?

RE: Shocks... KYB Monomax versus Rancho 9000, equivalent?
I save money where I can because I have to. If life events didn't happen, maybe I could be like you. Glad you can throw around a grand and not bat an eye, especially in this economy.

RE: Shocks... KYB Monomax versus Rancho 9000, equivalent?
I've read lots of positive reports about Bilstein shocks. I went Ranchos also because of reviews. Can't say I've been overly impressed. Not bad, but not great either, even with my lightweight camper. Marginally better than stock. I got a smoking warehouse deal on Amazon, so I went with them. Going with Bilstein next time.

RE: Lithium Battery Charging System
Everyone compares to Battleborn but fails to mention they use cylindrical cells,not prismatic..
Very true, costlier grade ‘A’ cylindrical cells of high uniformity (ain’t no free lunch), as does Aims…
3 tons
If I'm not mistaken, those Battle Born cells (and all LFP cells for that matter) come from China, but are assembled here?

RE: Shower Pan Reinforcement
I thought expanding foam was just to fill gaps, not support weight.
My pan has staggered 1x1s supporting it. Looks like a stilt home under there. Pretty cheesy looking, but seems to work.

RE: Lithium Battery Charging System
And this business of needing to spend hundreds of dollars on specialized charging equipment is false. If you already have a multistage charger that's all you need. Occasionally, they need to go to 14.5V. Many chargers already can do that. If not, no biggie. Get an inexpensive charger that can do 14.5V for 4-6 hrs and you're done.
As far as cost for raw prismatic cells, I'm currently paying $596 for four LF280K prismatic cells. Another hundredish for the BMS. $700 for 280Ah, not 100Ah, which is the most common capacity, isn't too shabby.
Yeah, if you insist on Battleborn, you're gonna pay, but you don't have to.

RE: Lithium Battery Charging System
Lithium is a Hassle? LoL it's the same procedure as installing acid batt. Sure, building a raw cell batt. requires a little more effort, but the payoff is far better than lead acid.
Price has dropped considerably for both raw cells and drop in's. You can get an 100Ah LFP for about $350. Probably less if you can catch a sale. That's less than the two 100Ah 160lbs AGM monster I replaced. Effectively the same Ah's.
I paid $400 less than two years ago and they've already begun to degrade. They were well taken care of. Not even used much, really.
Nah. With a 50% usable capacity that begins diminishing immediately at triple the weight vs. roughly 10-15 minimum year life to 80% capacity, even longer for the new K cells, lithium is absolutely less expensive in the long-term.
I do agree. If you're always plugged in, there's no point. But that's not truck camping. That's something else.

RE: Lithium Battery Charging System
I see you're taking compression pretty serious. I started out compressing, but after looking into it a bunch, it seems compression is of only some minimal benefit to longevity.
With the lesser cycle cells, you'll get some marginal extra life, or with used B or C grade cells. The K cells will last 17 years even if you mildly abuse them. If you really take care of them and constantly keep them in the 60-80% range, they are estimated to last 32 years. And that's without compression.
Not saying compression isnt correct and I know the manufacturers have always recommended it, I just can't see going through the hassle with these new LFK cells.

RE: Lithium Battery Charging System
"I don't do a lot of boondocking, but that could always change in the future."
I boondocked with wet batteries and now with a Lithium battery. With an adequate solar system recharging either type of battery is not an issue. Sure, my Lithium has more usable power and it recharges faster but those are the only differences I've noticed.
didn't notice the weight and size savings?
Right? He'll also notice a difference over time when money isn't leaving his pocket after just 400-500 lead acid cycles vs multiple thousands of cycles with LFP.
And the person "worried" about whether lithium batteries are safe... That's just silly. Lifepo4 chemistry is super safe and stable. The BMS takes all the worry out of it. You literally need to do nothing except keep it at 20-80% SOC for maximum life. You can even discharge to 0% if need be, so long as its not too quick. Get it charged back up at to at least 20% and you're good.

RE: Lithium Battery Charging System
The new EVELF280K cells are rated to 6K+ cycles. Building a pack of Four of these cells will provide longer service than any Lead acid. Combined with 3 or 400+ watts of panels, it's a no brainer.
After doing the requisite research and getting past the initial, kinda-steep learning curve of DIY LFPs and now that I've built one, the cost to energy density ratio is clear.
You can keep watering your cells. I'm done with that ****.

What I want to know is where are they going to get all the electricity from in the Southwest with all the reservoirs drying up and the coming blackouts this summer?
BTW, Tesla has stopped taking orders and deposits on the Hypertruck.

RE: 2019 Wolf Creek 850 Rear Tie down
Another wolf creek anchor point failure. Not the first one. Sounds like delam of the filon under the nose. My advice: unless you know how to fix it or are getting a really, really, really good deal...RUN AWAY!
I can recall a thread (and pics) here a good while back on this very subject, whereby some poor fella hit a bump
That would be anutami here on the forum.
