Thumbs up

that's right, no hard core off-roading or rock crawling , but how to make an egg more tolerant to backcountry bumpy trails, logging roads and ocasional cruising on cutlines. Any suggestios?

Things I can think of now:

-- moderate body lift of 4 to 5 inches, obviosly a new (straight?) axle (6000lbs rated?)
-- larger D class tires (how big I can go?)
(^^ those two to gain more clearance)
-- extra wide tires? (for soft surfaces) Pros/cons of these?
-- lighttening it up (looooong term project; for instance I don't see myself using owen in the bush, fridge? Eh.. maybe; but cooling beer in the stream requires way less mainenance if done with some due precaution and have insane idea to have wood burning stove in (some day)..., but I still want to keep my egg somewhat family-friendly, so toilet STAYS )
-- light skid plates (?) and
-- water/dirt/rock proofing on underbelly (will Kool Seal Elastometric Roof Coating do the trick, especialy if applied on plywood (prepping?)?)

Thanks!

It seems I may be one of the first in here, so here goes:
(disclaimer--this is only one man's opinion)

I would not bother with a body lift, as it won't do anything to raise the rest of the frame. I would likely start with the straight axle swap in whatever rating you deem necessary (6000lb sounded good), and I would use the longest flattest leaf springs I could get that are capable of carrying the weight of the trailer, plus gear, plus extras, plus an extra margin for piece of mind.

I suggest leafs because they are robust (logging trailers used them for years), and longer/flatter have better ride characteristics. One other beauty of leaf spring suspension is simplicity. You will be able to find parts almost anywhere, and a well installed setup will allow you to tailor the lift requirements to fit whatever tire you desire. Designing a suspension should also be a cakewalk, just weld on a couple of brackets to match your axle/spring combination to your wheelwell location.

I should've added that a body lift will also place unnecessary stress on the body mount bolts.

Thanks Paul

"as it won't do anything to raise the rest of the frame."

Sorry if was not clear; under "the body lift" I meant make a frame sit higher. Catchin a bump with an axle is one deal and most likely it will survive it; but crushed gray/black/fresh water tank is another...

Sorry for all those nub questions, just getting myself familiar with my egg...

Actually, from what I've read on most of these forums, your quest is unique in that you are trying to prep your egg instead of changing your needs.

As to skid plates, if the tanks are located close to the axle, then all you'd likely need would be a chunk of 16, or 14 ga sheet metal to deflect rocks.

Somewhere on this forum is a post about a small woodstove designed for marine use that has been repurposed for an egg. The stove is called a "Sardine".

For protective undercoatings, I'd suspect that any spray on undercoating would cover your needs unless you were planning to turn your Boler into a boat.

Thanks again! I'll look this "sardine" up. Remark on the boat was funny but I only want mild rock protection, washability and rot prevention (if it helps)

Steel? I was thinking aluminum, even perforated aluminum.

Any comments on wheels? Especially extra wide ones?

i am interested in seeing what you do here.

as for the "skid plates" i would suggest you use some 1/8" aluminum 60-61. it is strong enough to do what you want it to do. it will inhibit dents and bends and stay light.
it is my intention to use some of this on the underside of a box i plan to build under the egg. for me weight is very important so i always keep it in mind while putting these things together.

as for the 6000# axle.... holy schmokes! that thing will be bouncing down the trail. you might think about coilovers or something more fun. what is your budget on this project?
if you have welding skills and and handle some geometry, it would sure be neat to see a pair of coilovers and a 4 link on a boler.
it wouldn't be a cheap project, but it would be fun and challenging.

something like this

do a Net search for:
offroad trailers
offroad campers

They seem to have these more in Austalia than here in US. Searching thru their stuff may give you suspension ideas.

Also their is a website called Expedition Portal. This is where folk hang out that are more oriented to your goals. Might be something there in their forums about trailer suspension.

There has been some discusion in here on this topic. Reason I know is cause I started the threads or brought it up in other threads.

I believe you can go to my member info. Usually there is a button to go to a list of all the "threads" started by a member. Hit that and sift thru all my threads to find the ones on this topic.

You might also search this board in general for:

offroad
Unimog

These key words might bring you some stuff. I put Unimog in the list cause lot of my offroad stuff will mention Unimog.

Another idea is ... don't reinvent the wheel. Buy a used Miliary trailer and swap parts. Check Gov. Auctions. Buy one in the weight range of your Egg full. Not sure if that exist though.

I'm going to use an old Generator Trailer (M105A5) but that would be overkill for you. Maybe an old M101 (if I remember the numbers right) is more to your needs. Or even an older military "Jeep" trailer.

well....... on search the old Jeep trailer may be too light

Check it out here

By The Way... Steel Soldiers would be a great resource for military trailer info.

Oh and I do have a friend selling an offroad camper. Little heavier than an egg though. Ok... lot heavier than an egg. It's a Unimog box on a US miliatary Trailer. You could gut each and put the Egg stuff in the Military one for better camper interior. But you can't stand in it. Have seen folk put a rolling bar stool.. or a stationary... in this type setup. Infact that is what the Germans did in the Unimog. Rolling chairs on a track.

Erik: The 6000lb axle we're referring to is a straight (not dexter type) axle that has no suspension of it's own. The weight rating mostly refers to the spindle strength.

George: I love the simplicity of yanking the shell, and plunking it onto a military trailer chassis. If you were to leave the decking on the trailer, you'd also take care of the skidplate issue. The deuce-and-a-half trailers would be too large/stiff, but perhaps a 5/4 trailer would work better. Neat approach at any rate. Then again, you may just wind up adding a pile of weight.

Post pics when you've got it finished if you could, please.

Coach George, with all due respect
At the best of my knowledge I'm going to war ... yet. I would think the frame of military surplus trailer will do the trick if fitted under the egg but otherwise all you have suggested is an overkill for my goals which as stated pretty far from hardcore offroading, budget concerns aside (I don't go to dirt for the sake of digging a dirt, if I stuck it signals me it's time to back up and have a walk that's why I did not even bother lifting FJ - only added body armor and rock rails ). I have had enough military stuff so what I'm looking for is the reasonably comfortable movable dwelling - for family in summer and for dad and his buddies, big or small, in the fall and early winter. That's it. Place to sleep, cook, have a breakfast and dinner, protected from elements and curious wildlife. Sturdy enough to withstand prolonged trips on logging roads with no major damage taken. I will dig through your topics anyway, especially related to suspension, thanks for sharing.

"1/8" aluminum 60-6" exactly my thought, thanks Erik

Looked up Sardine stove (16kg)... I think with AB weather surprises I will be safer with Little Cod (25kg) and let's see if I will be able to break even weight wise if I get rid of furnace, stove (replacing it with 2brnr cooktop), fridge ... water pump...some cabinetry....toilet... Ahhhrrrr! Need do some math and start saving and wait for tax return or a lottery. I also imagine how those smoke heads will sound at highway speeds Just kidding, of course they are removable.

Before you decide to go with the "Little Cod" you might want to check out the Dickenson fireplaces that the yacht folks often use. They are small, safe and give a nice ambience with their visible flame, especially at night.

Dickinson also makes a solid fuel heater. However that model (contrary to what some illustrations show) does not have a window in the door. You can see a bit of flamage through the grille, I believe, but not the whole fire. They are considerably lighter and less expensive than the Navigator stoves, and might fit the bill depending on your usage. Of course they're less robust, too.

They're also bulkhead-mounted, as opposed to free standing.
