Breakdown of weight.

[markyodo]

I made a list of everything I could think of that would be part of a foamie build and store in the trailer permanently.
The number is weight (lbs) pulled from Amazon shipping weights all rounded to the next highest pound. If listed as 2.3 lbs then I chose 3 lbs.
Totals are without frame and with both steel and aluminum frames (5x8 & 4x8).

I wanted to get some feedback on this list as if this was a generic 4x8 foamie teardrop build.

I'm hoping to take my foamie to the scales soon. Maybe in the next couple weeks... When I do I'll have a better feel for your totals.

Weighing all the materials is a great way of guesstimating your final weight , and will be really close if you’ve been careful ... The Scales will tell what’s really going on ...

[markyodo]

I would rather have a "guesstimate" which drives the final design and purchase of materials before handing over my credit card.
Shipping weights, and product specifications are as close as I can get so far.

But of course !!! The Plan !!!

Shipping weights may include an estimate for packaging (?), but then again they look reasonable.

Except for the cooler. Unless you are just planning for a small 6-pack cooler and 5 lbs of ice, 20 lbs seems a little light to me. (But then again I am thinking of extended runs with 20+ lbs of ice + food and drinks in a medium size cooler.)

Does the "electronics" category include wiring? That can add up to several lbs.

Good effort on your part, but I have to agree, the scale has the last work after it is all said and done. When weight is a concern it pays to keep a watchful eye on every last thing you do. It's all of the added this and that, as much as the 'not' doing that puts the pounds on; ...not going to the extra effort to trim this or redesign that, not putting lower weight ahead of ease of construction... not buying or cutting/fitting the specific piece of material that will do the job instead of using whatever chunk of stuff is on hand and loading it on the pile of "stuff").

You seem to be on the right track.

? What's "Air 25" ....?

Do you mean Inverter or Converter? A converter converts shore power to 12 volt DC power to use in your battery-powered lights. An Inverter changes 12volt battery power to what can be used in things like a car stereo system, etc. (Your electronics isn't broken down, so, I'm uncertain...do you plan on a car stereo or other such things?) How you camp can make a difference on what type of electrical system you need. Do you plan on doing primitive camping yet want certain conveniences?

Also, I'm uncertain what kind of propane you will be carrying; but, if you are planning on one of those little 5 lb tanks, (I have one) the last time I checked, the propane to fill it weighs 5 lbs and the tank weighs 10 lbs, for a total of 15 lbs.

"Wood" weight can vary, depending on the kind of wood, thickness, etc. Even the color of the wood within species can change the weight, as darker and denser wood weighs more. Also, "Paint" can vary, depending on the type; and how many coats of paint you apply. If you look at the side of the paint can, it will often tell you not only how much the contents will cover but also how much the contents will weigh, once dry. Don't assume that it will only take one 5 gallon can's worth. You will probably want to apply more than one coat plus there may be touch-ups, etc, down the road.

Speaking of "wood", what will you be using as your deck? If plywood, what thickness of plywood do you plan on? Will you be using a wooden frame with plywood on top of it or will you be using something like a really thick plywood? Did you add in the weight for underside protection, such as Henry's or other black roofing goo/auto undercover spray, etc? Or, will the chassis have a metal platform/deck?

If you are building a foamie, won't you want to glue some sort of fabric to the outside? Is that what the 25 lbs of fiber glass is for? What about the glue/filler for that? Is that included in the 25 lbs?

As far as what KC said about the weights including the box, it's true. The weights given are usually the shipping weight, which does include the box. However, for your first "guesstimate" of weights, I would leave that in. There are always things that change, things that you forgot to add, and things that you decide to add after you get started with your build and those extra box weights give you a small "cushion" to help you achieve your final goal.

While I may have misconstrued some things, that's what I could think of off the top of my head. ...Maybe more later. I hope my comments help.

Thanks for the feedback so far.
Clarifications:
- All weights are estimated dry weights.
- Floor would be foam sandwiched in 1/4 inch plywood and weather sealed.
- 1 lb propane tanks (small)
- Not sure yet about canvas and paint or actual fiberglass, depends on what the final material of choice is and stability.
- Air is a guesstimate. 40 lbs for a small air conditioner, or a few good fans. Undecided.
- There is a separate line for wire spec'd at 50 feet of 14 guage.
- Trailer weight for Aluminum, NT lists the 4x8 as 195lbs. The extra weight must be the hardware required to make it fold. The 5x8 is lighter.

The other comments are very good feedback and much appreciated. Gives me lots to think about.
