    Wet underfloor heating system

    Lots of info here & on other EXP threads. Radiant floor heat is wonderful...without it in freezing conditions your floor is going to be COLD no matter how much you insulate it & blow hot air around above it...It's expensive & requires the ability to design it your self (or pay somebody to do...

    Wood frame campers...?? How do they hold up?

    "I cant wrap my head around how something shaped like a brick taking quite a bit of wind and such.. built solely out of would... could hold up." Research modern wood/epoxy boatbuilding techniques. Boats are under much greater dynamic loads & environmental stress than a truck camper will ever...

    Bottle Jack suggestions

    Only bottle jack I'd consider for any off pavement work would be a 2 stage type - these are pretty cheap...but you get the idea - 12"+ lift is actually useful once the dirt compresses...

    Replacing Rotting Wood Floor

    Consider possible outgassing with PT ply. Might just smell bad or might be a health hazard. Epoxy sealed ply is my first choice but in that location - structurally speaking - any ply is going to be better than that OSB crap. Get an oscillating multi tool - much better for the job since 1.you...

    Heater/Furnace Sizing

    Maybe not if the top of the tank is accessible - with a Espar it's just a small bolt with a tube running through it - so just drill & tap for the bolt.Moe

    Installing an Espar without hooking up to engine plumbing

    Actually no it doesn't...My Webasto TL17 when mounted independently (not plumbed into the engine cooling system) requires just 3 gallons as a minimum. So you have to find the volume required by your specific model. Moe

    Installing an Espar without hooking up to engine plumbing

    Not tapping into the engine coolant circuit is common & makes the install easier. There's a minimum volume required - it's in the specs but the larger the coolant volume the less short cycling you'll have so the bigger the better up to a point...I've got a 5 gal tank in addition to a 2gal...

    Bleeding an Espar hydronic system

    Really appreciate the info! I spent hours & hours bleeding my system using 2 valves located at hose high points with a hand vacuum pump to "encourage" the air to be sucked out when it passed by - this is in addition to having the expansion tank located at the highest point. Sounds ridiculous &...

    Heating a pop-up truck camper?

    "As far as draining the starting battery....I thought my camper had an isolator already to separate the truck battery from camper (power is pulled from the AUX on the 7 pin connector). I would have thought that me draining the camper battery the other weekend would have left me stranded at the...

    Heating a pop-up truck camper?

    "Add a second battery, I don't have room inside the camper, so to add one I'll store it in the truck bed infront of the rear wheel well (with a marine box strapped down), and have a quick disconnect to the house battery. Since both batteries are outside, I can use a true deep cycle (not marine)...

    What does "Light Weight" mean?/

    Nothing wrong with a massively insulated camper - but the costs are weight & loss of interior space. Weight because the price of a core material that's both structural & with a high r value is well...high - so you need to use your non structural foam with an internal frame that's never going...

    What does "Light Weight" mean?/

    Great intelligent post! "So why isn't 1", 1/2", or 3/4" composite being used in building truck campers?? It is widely used in boat building." (or 1/2" -3/8"- 1/4" -3/16" 1/8th" panels...) One reason is the simple bonding techniques used to build a simple box aren't well known and are radically...

    What does "Light Weight" mean?/

    - x2! Coming from a boat building background I find it inexplicable how the rv manufactures have ignored the composite material advances now widespread in the marine industry. Stick building? Still? Alaskan Camper is still building with 1950 era methods...It's a shame I tell you!!!Moe

    Cedar shiplap pop-up truck cap

    x2 Check out the hybrid composite construction of many of the builds on the ttnt forum.tnttt.com/ Thin ply or glass skins on foam with light wood framing is the lightest build method for your skill level. They do take some design thought to pull off successfully but the skill level is only a...

    Soft shackle vs iron shackle

    "Reasons to not get rid of all the extra iron in the hook and D-shackles?" Only 2 reasons I can think of - 1. If I had to winch as a regular job I'd want the convenience & durability of steel. 2. It's necessary to have steel when hooking to a steel edge on a vehicle frame for instance. I make...

    Baseboard heat or other radiant heat with no fan using espar for heat source.

    I'm gonna sound like a PITA whiner but...the noise of the webasto annoys me...I'm finally in the Big Empty, dawn & maybe birds & maybe it's just really quiet. Man...what's quiet worth these days? To me - a LOT. So getting the camper warm breaks the beauty. The webasto is not loud by any means -...

    Baseboard heat or other radiant heat with no fan using espar for heat source.

    When sleeping in freezing temps I generally run 2 of the 4 computer fans all night - all 4 if necessary. Necessary would mean to keep the cabin temps above 45F-50F while firing the webasto as little as possible, mostly because it disturbs my sleep somewhat. I set the webasto thermostat to 45F or...

    Baseboard heat or other radiant heat with no fan using espar for heat source.

    "I like this idea too. Should prevent hot spots on the floor. My other thought was to use aluminum sheet over the tubes to spread the heat and still have the planned wood floor over that." The aluminum sheet is an great idea & I wished I'd tried it on my floor. In my floor the tubes are 4"...
