love the post...you definitely have a very good understanding of whats going on concerning a conversion.
i live in south louisiana, so the oven reference couldnt be any more correct. the trailer just sitting here with the heat and humidity is stiffling, so ventilation is very important. my old cargo trailer has a vent on the roof and it helps a little, but a vent fan, like mr. fantastic, would be better. since i dont want to penetrate the roof (yet) i decided to just install a bilge blower to suck in air thru one of the existing 3" vent holes on the side. suck in air from the bottom rear vent and then let it naturally push out warmer air out of the front upper vent. should serve to the same effect of having a roof vent? can only find out by trying it out and seeing.
very good point about any leaks. when i bought the trailer, the distributor for cargo mate had a plaque in their sales room showing a cut away section of the trailer walls. this one is a composite material kind of waffle shaped and sandwiched between two metal panels. the panels do not have any rivets or fasteners, so it should be pretty much bullet proof concerning water leaks. i bought a small toy hauler new in 2019 and it also had the composite sides which are bullet proof...but then it was cut out for windows and doors and that is where i am having problems. windows are leaking and one of the entry doors is all warped and weird and you can see a big bunch of light come thru around the seals where the door is crooked and wont close right. i sent it back to the manufacturer and 6 months later received it in worse shape than i sent it and then they tell me the warranty is expired now. i'm a decent builder for the most part so even if i install a window properly, i still might get leaks and have issues because the actual windows and doors are jacked up from the start.
the way the wife and i travel, we basically get up and do coffee/breakfast and out the door. we generally get back at dark and then take a shower and go to bed. we did 10 days in north georgia a while back and we always got back at dark, so windows really arent a deal for us since we are really just in the trailer to sleep. i am looking at the 2-hose portable ac unit for cooling. basically suck in outside air to cool the condenser with one hose and then blow out the hot air thru the other hose...a better design than the single hose units. that should cool us off nicely and can be ducted thru the floor instead of a roof mount ac.
some of this might not work that great, i dont know until i do it. but, by being modular, i can change things easily. if i decide i want a drop in stove, i can easily remove the kitchen module and take it to the shop and make my mods and easily bring it back in. i dont like RV build outs because they use luan and furring strips with staples to build everything, so i really hate going in behind what the manufacturers do.
this conversion is going to be very unique for the way we travel, so i really wouldnt expect the average folk to like it. most people would want windows and other items normally found on RVs. hell, i might even want that myself further down the road. as long as i keep things simple and modular, i can always make changes without much hassle.
really appreciate your insight
@deagle and hopefully you will be glancing at this thread ever now and then and offering any advice/ideas. since youre doing a build out as well, hopefully we can be of help to each other. might run across a really cool idea or piece of gear that will be helpful.
and yeah, you are right on about the play in e-track and it could be a problem using the e-track brackets...since mine came with the e-track and i dont want to have to change it, i just found that if you take a 1/2" carriage bolt and grind down two opposing sides, you end up with a T-bolt that you can insert and rotate 90 degrees and it will lock in flush to the e-track and not rotate since the square shoulder of the bolt fits into the slot of the e-track and will tighten up really snug with no movement. chap and easy and only takes a grinder to make.
