Constructing A Light-weight, Aerodynamic Cargo Trailer For Extra “Boots On The Floor” Protection – CleanTechnica Acquire US

Again in March, I ran a profitable fundraiser to assist collect extra “boots on the bottom” protection, together with every little thing from occasions and corporations to product opinions in superior places. I didn’t meet my total purpose, however I did get sufficient raised to get a really strong begin. Since then, I’ve been placing any cash I might collectively to get the previous couple of issues collectively.

Sadly, all of that tenting and different gear is taking on a bunch of area round my home. As a result of I targeted on extra of a glamping setup, with insulated Shiftpod shelters, we’re speaking a few fairly important a part of my lounge! I had initially deliberate to only purchase a small cargo trailer to maintain all of it in, and to drag behind the Bolt EAV (It’s an EUV, however I take it on adventures, so it’s now my “Electrical Journey Car”), however I wanted to save cash and I figured I might construct one thing smaller and lighter to attenuate vary loss.

The Trailer

To economize and weight, I began out on the lookout for a Harbor Freight trailer. They’re not the best they usually can’t deal with quite a lot of weight, however their light-weight modular development (a bunch of aluminum extrusions bolted collectively) makes for an excellent platform upon which to construct a light-weight trailer. However, they’re out of inventory nearly in every single place, and even used ones had been tough to come back by.

Sadly, the one factor I might discover was components. Some got here from a broken trailer with no title I discovered for reasonable. Others got here used. A couple of components even got here from Harbor Freight itself. However, after a pair months of scraping issues collectively, I managed to piece a trailer collectively.

Now, the following steps will probably be to construct my cargo and tenting field on high of it. I’ll be increasing the body out just a few inches on both sides to extend the inside room a bit. Then, I’ll placed on some comparatively skinny plywood decking on high to carry all of it collectively and beef the construction up a bit. Then, I’ll be constructing a really skinny wooden body to carry all of it up and bolt issues like doorways and a slide-out kitchen onto.

Lastly, I’ll construct the outer shell with “poor man’s fiberglass,” which is a composite of froth and canvas or window display screen, glued collectively to make for a really gentle however inflexible and powerful exoskeleton. Many individuals have constructed trailers of varied sizes utilizing this technique, so it’s a confirmed solution to save on weight with out dropping power.

It will then be coated with Raptor Liner to maintain the climate out.

Effectivity has been factored in at each step. I’ve deliberate the general form to tuck properly behind my Bolt and reduce aerodynamic drag. Weight ought to be under 1,000 kilos loaded. It’s additionally using on some very skinny tires that ought to get low rolling resistance.

I’ll do some replace articles over the following couple weeks as I get the entire thing put collectively!

The First Journey

I don’t wish to rush into an extended journey with iffy charging infrastructure after I haven’t discovered what my vitality consumption appears like, so I’m going to begin with a carefully-planned shakedown cruise. I don’t like to inform folks about journey plans forward of time for safety causes, however I’ve chosen a stretch of highway with plentiful charging alternatives the place I’ll be capable to check the car at completely different speeds.

On this journey, I’m going to attempt to load issues about like I might for the longest journeys. I’ll have 2 or 3 e-bikes securely locked up, all tenting gear, a photo voltaic generator I’m about to overview, tent HVAC, and even a small fridge. I could even take a pair canines and different pets alongside for good measure.

I’ll use the OBD-II connector and have A Higher Routeplanner monitor the CAN bus for vitality utilization, so I’ll not solely have an excellent image of my vitality effectivity, however I’ll be capable to plug my future journeys in and get correct journey plans sooner or later.

One other Factor I Hope To Accomplish Right here

In case you learn my articles right here lots, you most likely discover that I speak about towing lots. However, as I identified in one other article, we are able to’t simply throw the concept of effectivity away simply because towing occurs. We merely should not have the battery provide out there to place a 200+ kWh battery in each driveway, and the economics of even attempting to do this simply don’t work out.

However, that doesn’t imply we shouldn’t ever tow. In truth, utilizing smaller and extra environment friendly EVs to tow every now and then signifies that we don’t must be driving vans and enormous SUVs the remainder of the time. However, making that method work the way in which it must work would require environment friendly trailers, which will probably be a really completely different method than a lot of the business is taking proper now.

It’s my hope that by constructing an environment friendly cargo trailer, we’ll be capable to show that we don’t want large, heavy trailers to do actual work and have actual enjoyable. By getting the load down and getting the form proper, it’s doable to do quite a lot of issues with a smaller battery pack. For me, it’s going to be a 65 kWh pack, which is greater than 3 instances smaller than many individuals suppose is totally wanted.

Evaluations Are A Large Half Of This

We’ll most likely get into this extra in one other article, however opinions are an vital a part of what we do right here at CleanTechnica. Whereas many opinions can occur regionally, there are numerous cleantech merchandise, particularly e-bikes, that deserve a way more in-depth check away from house.

In case you work for a corporation that sells e-bikes, photo voltaic mills, or some other product that you simply’d prefer to have examined on the market away from the town (together with some stunning scenic locales), remember to attain out to us! We’re placing collectively some nice choices for firms to get an goal overview with out breaking the financial institution to get that executed.

I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we carried out a restricted paywall for some time, but it surely at all times felt fallacious — and it was at all times robust to resolve what we should always put behind there. In concept, your most unique and finest content material goes behind a paywall. However then fewer folks learn it! We simply don’t love paywalls, and so we have determined to ditch ours.

Sadly, the media enterprise continues to be a tricky, cut-throat enterprise with tiny margins. It is a unending Olympic problem to remain above water and even maybe — gasp — develop. So …
