Believe it or not, S1 and S2 glass are not that much heavier than carbon. The advantage comes in being able to use less of the carbon, while retaining or even increasing strength. Vacuum bagging allows the exact (minimum) amount of resin to be used, where wet layup almost always has excess...

I figured that is what you did, lol. If the OP is concerned about the skins delaminating from the foam, then I would encourage some research and/or testing to ensure proper bonding between materials, compatible adhesives or tapes, etc. If the concern is pieces of foam tearing away from "other...

Uhhmm, I think one of you guys read something wrong. :D A total of 21 holes are drilled into a 4' x 8' sheet of foam with grid lines on 12" centers. Holes (0.375") drilled at each line intersection are filled with epoxy, presumably to a 2" depth. Are you trying to make a contact point like a...

^^ Have you done any heat loss calculations or do you have an approximate R-Value, U-Value or Lambda for your new camper? What temps have you used it in and how much energy does it take to heat and/or cool? Charlie Aarons posted a very interesting calculation a few years ago for his Unicat...

No sir, no pics of that exact rod end being used as a trailer hitch. I have seen their large heims and IIRC, Poly Performance makes one even a bit larger, used on monster hill-killing, rock bouncer style buggies and they hold up fine. So, the strength is not an issue, for certain. If I were...

This has been discussed here and over campfires and beers many time. It's good to see someone having a go at it finally. For the reasons that you mentioned (compatibility, frame, engine, etc.), everyone seems to be scared. I do not believe that these differences are impossible to overcome by...

I can forgive you for not clicking on the link or reading thoroughly or possibly for having concerns about a heim failing in that application, a trailer coupling. For clarification, this is the heim in the link above. Just try and break it. EDIT: It is far superior to the $50 bolt on trailer...

That is an interesting layout. I don't think I have ever seen a box built quite like that.

You will be hard pressed to find evidence of a rigidly mounted camper causing a frame or box failure for two reasons, IMO. First, few people mount camper boxes that way and 2) this market is so small already, you simply do not have a large dataset from which to pull. If you were asking a...

West's 610 Epoxy or appropriate VHB tape. 5200 does not love aluminum but it will work in your application. Call Tech Support or an application engineer at your preferred vendor, tell them what you are doing and get the right product for the job. If you want the cheap/DIY route, you could...

Trailer pins do not prevent theft. A 4.5" battery powered angle grinder with a cut off disc will have that pin laying on the ground in less than 30 seconds. Something like this for a trailer hitch, made specifically to work with your trailer and vehicle will almost guarantee you that not only...

Find a 330 pound dude, sit him in your car without a seat belt and drive erratically. Report back. Baffle your tank with foam suitable for potable water or have a tank made with baffles inside.

While I am neither a structural engineer, nor an expert in composites, I do have some experience and a basic working knowledge. I am also bored at work today and am pretty good with math, so here goes nothing. In order to do this correctly, you need a LOT of data; data that I do not have. So...

Fixed it for you. There are plenty of quality RVs made on MDT chassis and commercial bus chassis, but as you pointed out, many are not. Just like everything else in life, you get what you pay for. A 100k motorcoach that is 40 feet long and designed to be used a few times per year simply does...

Are the windows completely custom or simply a stock design made to your dimensions? Post a few pictures of them if it's not too much trouble. You have probably done your research by now, but a 6BT is a powerhouse and power is only limited by your checkbook. They are great motors; simple...

There is really no way to offer an "average cost" or to estimate a cost, IMO. How do you want to build your panel? Do you want structural foam like CoreCell or cheap EPS? Do you want a soft top, fixed roof or lifting hard top? Do you prioritize weight over heat/sound insulation or is ease of...

LOTS of engineering goes into NVH or Noise, Vibration and Harshness, in the automotive world. For these reasons, you barely hear a modern car at idle or when coasting down the road. When you stand on the right pedal, some sound comes from the intake, some from the exhaust and some from...

Try to find something already converted. White Feather Customs, Quigley and a few others such as Advanced 4x4, Boulder vans and Tulsa Truck all do conversions. You are going to be looking at something in the 15k - 30k range depending on the builder and what all is included. Depending on what...

I have a DIY composter in the basement and will post pics if I can find them. The urine bottle is just a gallon milk jug with a funnel feeding it. If you are properly hydrated, your pee is about 90 percent water and should not smell like Golden Grain. Distilled vinegar can be added after each...

This. Do some research into how companies such as Unicat, BiMobil, Bliss, Boxmanufaktur, Action Mobil and others build boxes. They are using an industry standard 40mm or 60mm thick panel, likely built in-house or by a partner. Panels are joined using adhesives so strong that the panel will fail...
