I have Yak Tracks on two fiberglass shells. I installed the tracks parallel to each other to make it easier to move things around as my needs change.

I stopped and looked at the Rigid boxes yesterday and they are pretty decent, but agree that they are not real space efficient. Lots of ribs and lips and tricks to stiffen the plastic structure, and that leaves a lot of wasted nooks and crannies. The bigger boxes in the line are better, but...

I only carry one, and it is an Amerex 2.5 pound Halon, mounted next to the driver's seat so I can grab it on my way out of the cab. Halon is getting scarce and expensive (banned I think, so will eventually go away). Halotron is the new substitute, but not as efficient as Halon. There are all...

Blue Sea stuff is the best. I just don't want automatic stuff on my truck. My solenoid is switched from a toggle on the dash, and my house batteries are controlled by a Blue Sea rotary switch.

My PM1 went three years, almost to the day. Did not fail because of a charging/maintenance problem, but seemed to develop a bad cell. Sears would not warrant it, but Odyssey did. Really good customer service and support from Odyssey, Sears not so much. I am thinking we should start an...

Your alternator will be fine. My Dodge probably had the same 160amp alternator (until I upgraded to a 270 amp), and I ran that 160amp alt for ten years before I upgraded. The old 160 is still just fine and is in a box as backup if needed. It originally charged a single Grp 65 flooded lead acid...

I have been running a pair of 34s in my old GMC for about 18 years with no issues, but I have an isolator in the system. Simple solution is to wire the two batteries with a rotary switch (Blue Sea Systems or similar) so that you can isolate the batteries. You just need to remember to keep the...

Costco selection seems to vary significantly from store to store. The are pretty careful about stocking stuff that appeals to their local market demographics. I can't get a decent battery at my local Costco.

I have a couple of Grp 34 Yellow Optimas that I retired because they would no longer start my old truck, even in a dual battery setup. They sat around for a couple of years and then I "woke them up" when I got my Ctek 7002. Optima spec says these batteries are fully charged at 13.1 OCV, and my...

Renting for 5-6 weeks will probably pay for a nice used one. Check with the RV rental places, see what they have available.

I don't think so. The charging specs are on the last page of each battery's tech data, and the 10amp max is listed under "Battery Charger (Constant Voltage)" rather than under "Alternator." And they also have a recharge time chart showing time to recharge to 90% from a "100% discharge - 10.5...

Found the Optima specs, and the Grp 34 Yellow and Blue (dual purpose) appear to be identical except for terminal configuration. This is for D34 Yellow top post D34/78 Yellow dual terminal (GM side terminals) D34M Blue dual purpose marine with top posts and marine studs (light gray case) All...

That's not what Optima told me last summer when I was buying batteries. In that case I was buying Grp 34s as my house batteries, and I had already ruled out the Blue Grp 31M as my starting battery. Word from them was that the starting Blues (Grp 34) were internally the same as the Reds, and the...

Yep! And they weigh less than the Odyssey or Northstar, so less lead. But I still bought Optima Blues for my house batteries because they are just so much less trouble.

That's very interesting. My Dodge has what is probably the same temp sensor, spring-loaded on the bottom of the battery tray. Most of my driving with this truck is in summer temps in the southwest, and even with ambients well above 100F, I'm still seeing system voltage consistently in the...

Optima Blue Grp 31M Dual Purpose: Odyssey 2150 31M: At least per published specs, the Odyssey 31M has 1150 CCA vs 900 CCA for the Optima, and 205 mins Reserve Capacity vs 150 mins for the Optima. Even allowing for marketing hype and different measurement conditions, those seem to be pretty...

Optima makes the Blues in both starting and deep cycle versions. The only visible difference, other than the part number, is the shade of gray on the case. Even the Optima dealers are confused about the Blues.

I have been using Optima Yellows since about 1999. They were very good back then, then hit a rough patch with very spotty quality after they moved production to Mexico, and now they seem to be OK again. For my use, I prefer the Optima Blue Dual Purpose because they have the marine studs that...

Definitely different trucks, but I could swap batteries between the trucks to equalize things for comparison purposes. Not going to happen, though, because these things are too damn heavy to be moving around. Batteries are the same age, acquired within about thirty days of each other, one last...
