Found the answer posted earlier. No panel detail: https://australmotorhomes.com.au/slide-on-campers/truck-mount/savanna-3-5/

~$47k full up in $US, is certainly a good price. I'm very leery of anyone not giving panel details, though.

A fun place to explore:

@gator70 can you share the specifics on the 4wd conversion? For those of us looking to convert Isuzu chassis there's a lack of choice. So any info you can share is super valuable

I've spoken with RidgeRock over the phone and requested a quote via email with available options(havnt received it, its been a month). All I he told me over the phone was $29k for the conversion but really no real detail on what is included in the price.

What front axle is used? What transfer case is used? Is the rear axle kept stock? What gearing was used.

I bought the front locker and 5 super single rims in addition.

Later I will upgrade to king shocks.

Early in the thread i was going to do this with a California shop. Using both f450 axles. When adding up the prices, labor ect. It was cheaper, but not by much. And the risk of issues along the way obvious. I liked the warranty.

With all of our rigs, many options are available. I choose to simplify as much as I could.

Yes I changed direction a few times. So far it was the right choice.

 

[gator70]

I'm about 90% done

Were building the subframe now. I prebuilt all six spring mounts. When it sits on the truck frame we will be done by days end.

Wish I knew how to lift the habitat on the truck frame without a crane.

BTW, gearing is matched to the OEM rear axle. Both Diesel and Gas are different. And the NPR HD is different than the NRR to my knowledge

Bolt pattern on all fours is stock Isuzu

The FTR is really cool - Wish I could afford it

(i'm going to do mine in a nose wrap like this in the habitat color)

 

[SootyCamper]

Yeah the FTR sure is cool!

But double the price of the N-Series. Big bonus of the the N-Series diesel you can get service basically everywhere in the world. The cummins in the FTR has pretty good service network but no where close to 4HK1 in the N-Series.

Thanks for the info Gator cleared up some unanswered questions I had.

You ordered a house without knowing the materials in it or how it's put together? That seems kinda risky to me. What if it's just typical RV construction of laminated panels?

NO - NOT CORRECT

 

[rruff]

NO - NOT CORRECT

Then what are the materials and how is it put together?

It looks like EPS foam but what are the specs? What are the specs for the skins and adhesive?

 

[gator70]

Security installations

What do other folks do?

I have a few plans. Yet I want to do more

Risks

Bad people
Rig theft
Rig items small theft

Wild animal damage

These are the tires I bought

Is anyone running this tire?

 

[gator70]

Security device I look at

(This slides around the leaf spring and slides through a wheel with a ventilation whole)

Or some similar fabrication

128Q is 1800kg maximum load depending on weight, on the rear axle you may be tight

128Q is 1800kg maximum load depending on weight, on the rear axle you may be tight

Thanks i'll be underweight . The rating on the rear is 3970 lbs a tire. So 7940 lbs on the rear. By manufacturers spec.

Currently I'm at 1800 kgs with the habitat "dry" - this is according to manufacturer

A tire marked "128Q" has a load index of 128, meaning it can support a maximum load of 3,970 pounds per tire, and a speed rating of "Q," indicating it's safe for speeds up to 99 mph.

The truck empty is 5900lbs

Due to crew cab the truck is 55% front, 45% rear weight distribution.

The habitat due to the cab over bed is 55% rear, 45% front weight distribution, and that changes with water tanks full.

Can I guess I have an extra 1800lbs of payload over the rear axle?

I'm going to build a storage compartment between the rear bucket seats and store heavy stuff there as practical.
