    Pro-Rig V2.0 - Home Built Compact Composite Pop-up

    Oh, that's an epic finish. Looks awesome. I'll try the tung oil. Figures that more sanding is involved though :squint: I'm starting to think about 75% of my total time on this build will be sanding before all is said and done. So it goes...:)

    Pro-Rig V2.0 - Home Built Compact Composite Pop-up

    Made a little progress today! Got the first seat/hatch in finally. Pretty happy with it. One down, one to go... Also took a big leap and went for it with the wood veneer on the table. We chose zebra wood. Edges will be trimmed in dark walnut. Brushed on the contact cement and let it sit for...

    Pro-Rig V2.0 - Home Built Compact Composite Pop-up

    Well, precious little to report actually. Life and work getting in the way of progress lately. Did get out to the desert to see some of the "super bloom". Good stuff. Everyone is enjoying the flowers. Would have been a perfect trip for the camper. Better get back to it!!

    1 Bored Clerk's DIY Camper

    I've found that these little squeegees are great for working the epoxy in/out of the cloth (stiffer white ones) and work well for fairing as well (slightly softer yellow ones). Less than a buck each a lot of times. Most fiberglass supply places will carry them. You can get similar ones...

    Here's what it looks like before epoxy. Hoping epoxy gives it a nice shiny look. Should be real tough too.

    Pro-Rig V2.0 - Home Built Compact Composite Pop-up

    Floor will be some sort of faux-wood vinyl planks. Liking the distressed looks but final decision goes to my vice president of interior design, AKA Sheri; AKA the girlfriend :) Counter top is 3/4" plywood with a DIY granite finish (natural sponges and hobby paint). Got the paint on, it's...

    Pro-Rig V2.0 - Home Built Compact Composite Pop-up

    Busy, busy, busy... Yesterday got the roof out and sanded it down. Today, I busted out the epoxy and glass cloth and got a layer on. Brace yourself for the stunning transformation :sombrero: Ta da! While that was drying I wrestled some more with the interior cabinets. Progress was made...

    Ski Bum Truck V2.0, F450 Rough Road RV

    Looks like that schematic is for monitoring two battery banks, which I think is a pain in most vehicles. If you want to just monitor your house batteries, everything (chargers, loads and chassis ground) on one side, house battery (-) to the other side of the shunt. That way you measure amps in...

    Ski Bum Truck V2.0, F450 Rough Road RV

    Do you have a link to the mattress? How do you think it would work doing double duty as seat cushions and mattress? I don't have much experience with memory foam but seems like it might be too soft for sitting on? Wonder what kind of foam the fancy RV's use on convertible beds?? Hmmm...

    ultra compact slide in / sleeper

    I'm half expecting to see Neil Armstrong step out of it. That's one small step for a man...:sombrero: Looks super cool. Doing all the fancy angles really paid off aesthetically.

    Thanks for the pep talk guys - some days are better than others in the "shop", but it's all progress.

    Dual Batteries with Lithium - a cryptozoological study

    Good points and good questions grizzly. I think dropping lithium batteries in to charging systems set up for lead acid is going to lead to significantly shorter life spans. Already lots of complaints out there about capacity dropping off after just a few years of use. Float charging is slow...

    Pro-Rig V2.0 - Home Built Compact Composite Pop-up

    Some good progress this weekend. Roof halves being bonded together: Came out nice and rigid and not too heavy. Ready for a layer of glass on the outside and paint on the inside. While I had the tube of epoxy out I glued in all the aluminum trim for the interior cabinets and today installed...

    Dual Batteries with Lithium - a cryptozoological study

    For some this is a good reason to not go LiFePO4 but for most there are ways around it. One little detail to clarify, it's the temperature of the battery, not necessarily the air, that is the important factor. When the electrolyte in the battery gets close to 0*C, that's when you mustn't...

    Pro-Rig V2.0 - Home Built Compact Composite Pop-up

    Depends on what the cutoff level of your BMS is I guess too. My BMS kicks in at "you're about to permanently destroy your battery" level, not at "you shouldn't really go lower than this or you might damage your battery in the long run" level. BP is for the latter in my system. Similar approach...

    Pro-Rig V2.0 - Home Built Compact Composite Pop-up

    Okay, a little actual progress to report. Got the slide-up out and got a layer of fiberglass on it. Other than a big Santa Ana wind kicking up just as we were getting started, it went okay. For battery geeks like me: I did a little testing on the battery setup. After a full charge, it took...

    Dual Batteries with Lithium - a cryptozoological study

    Here's a calculation based on recent prices/availability in the US: I just bought four CALB 100AH cells with BMS and Cell balancers for $653. Rated at 4,000 cycles at 80% discharge = 320,000Ah over the life of the battery $0.0020 per Ah Still lots of reasons not to use lithium, but cost...

    Pro-Rig V2.0 - Home Built Compact Composite Pop-up

    Not a hijack at all! I like the discussion. Only question I would have is if the Battery Protect is redundant given the BMS-controlled 9012 on the load side. Maybe you want two different tiers of disconnect though? Other than that, it all makes good sense to me. That SmartBMS looks like a nice...

    My next new build is about to start - V3 Explorer - Feedback from the group needed

    Truck looks awesome! Look forward to details on your battery setup. Is it a packaged setup like Victron or did you build your own system? I'm just getting my 100Ah DIY lithium system up and testing - I'm always looking for more info and examples... matt

    Dual Batteries with Lithium - a cryptozoological study

    Good discussion going here. For those interested in a very comprehensive take on lithium house batteries and charging challenges in vehicles take a look here Couple take home-messages from all my research: (1) there is certainly a lot of bad info out there on the interweb from so-called...
