Question How is this design? / Espar? Mule bags? Cruise 130?

Hi all

QUESTIONS

one) Is anyone using the Adventure Wagon MULE Overhead Storage Locker bags for pantry stuff?
(see below for details)

two) What do folks think of the design (see below)

three) Any alternatives to the Espar (gasoline) for hot water for the shower?

four) Anyone have a ISOTHERM Cruise 130? How is it?

DETAILS:

After considering at a full interior build (too expensive)….. and also a ‘basecamp’ build… I think we have settled on something sort of half way in-between.

Below is the what we would like to do.

I’d welcome any thoughts as to what I may be missing / any oversights.

The build will likely be either Sportsmobile Fresno… or American Van Works Stanton CA.

THE THINGS WE ARE 100% SET ON:

22’ high roof 3.5 EcoBoost Transit gasoline. (ordered to our exact specifications)

Dynamat or RoadKill for sound dampening. (SMB recommends either one)

‘extreme weather insulation’ (for both heat and cold) (what SMB calls it)

single Captains chair behind the driver for our daughter. Ideally with swivel, if that is possible (tbd)

Dual slider doors. (if we can do that, with the bathroom where it is in attached image - ?)

No black tank. (Port a Potty instead)

Espar gasoline for hot air.

VERY LIKELY:

Solar panel(s) on the roof, controller

Aux. Battery Kit w/ Std Deep cycle 105 amp hr group 31 or 27 battery

Shore power

Built in surge protector

Inverter - 2000 or 2,800 watts.

Awning over passenger slider.

bathroom (shower) 24” x 36” or 24” x 33” (SMW recommends either)
bifold door on shower - due to clearance issue.
Maxx fan in bathroom.

Espar gasoline for hot water [showers only] (unless there is a better option?)

Grey tank.

No blank tank. (Port a Potty instead)

MOAB Elevator Bed for Transit - big brown rectangle in attached image.
This would give us flexibility if we wanted to haul stuff.

Our daughter would sleep on the floor, partially or wholly under the MOAB bed, on a mattress on the floor.

windows in the sliders, and an opening window in the shower stall, but no *big* windows rear of that.
small awning windows, up high, on either side.

ISOTHERM Cruise 130 Elegance (or similar) Refrigerator on passenger side.

For storage - MULE Overhead Storage Lockers ($400 each, flexible)
mounted to L Track. More flexible and much cheaper than cabinets.

https://adventurewagon.com/collectio...ker-light-grey

POSSIBLY:

Pedestal with sink + single burner propane burner, 2 gallon fresh jug below, 2 gallon grey below, manual hand pump for water, connection for disposable small propane talk below. Self contained.
In “Cabinet E” or “Galley” in the attached image.

Safari Straps to contain anything in the garage, below the MOAB bed.

Thanks for any and all thoughts

John

It might be preferable for your daughter to sleep either across or back to front the front seats if you can make or buy a bed to fit across there. Perhaps a triangular shaped bed incorporating the third seat for support if she's tall so she would have lots of room diagonally. Some examples:

Roadtrek Front Bed Setup

That will give you more storage under the bed and unimpeded aisle access to the bathroom and exit doors. The floor soon gets dusty/dirty in my van and would also likely be the coldest area.

You could save some money by going with a 3 stage converter to charge the batteries instead of an inverter/charger. I like the idea of a high powered inverter but it's probably not necessary in your design as you don't have a microwave oven or air conditioner etc. and don't have the battery capacity to supports item like that.

If you use an Espar hydronic system such as the D5, you can use the same hydronic loop for cabin heat and on-demand hot water (using a flash-plate heat exchanger). The Rixen's system in our Great West van (also used by ARV) works that way.

You may want to take a good look at projected power use vs your use patterns.


A single gp31 is only in the 120ah range, so the 2000 to 2800 watt inverter would really only be able to run with the engine on, and only if the wiring is large enough to supply 100 amp to the coach. The Isotherm will likely use 30-70ah of battery per day, leaving little for anything else.


I thing you will need more battery, at least double, probably the more common two 6 volt golf cart batteries that are in the 220ah range. You need to be able to recharge them reliably so that is part of the use pattern and equipment, so shore charger if you often plug in, solar for at least some of the recharge capacity, and some sort of generator for the rest if the others can't keep up.

Thanks for the great thoughts so far.

And

P.s I am not sure if the brown rectangle is the correct size for the MOAB bed.

Might be a little bit long. Front to back.

Thanks for the great ideas.... we bought an inflatable bed for her to sleep across the front beds in a rented Sprinter... unsure as to how well it would fit in a Transit. I seem to recall it says "fits Sprinter and Ram"

but perhaps we could make it work. Or something similar. She said it was very comfortable, and she loved it.

and

I should have mentioned - I would likely end up sometimes camping / traveling by myself, and carrying a very large amount of electronics with me, so i'll need the 2,000 or better yet 2,800 watt inverter... for running the gear for maybe 5 hours max.... any guesses as to what sort of battery capacity needed to pull that off?

guess I had better do a spread sheet of the gear power draw to calculate the watts drawn by each piece of electronics.

thanks

Thanks much... are you happy with how your Rixen system works?

Could you post the exact model #? if that is easy.

do you happen to know if there is a *gas* 2 in 1 Espar unit, as you mention?

any downsides to your setup?

Thanks. I'm a bit confused as someone (evidently incorrectly) told me you always needed two separate Espars to do what we want.

thanks.

We have the 22' Transit. With a full-length bed - that is: 76" longitudinal, there is only room for the sink and stovetop before getting to the sliding door opening. I'm afraid that your current design may not have sufficient room to exit via the sliders. You might also ensure that you can reach and open the rear doors regardless of the bed position so that you can exit in a hurry if the front is blocked.

1200 watts is 100 amps, so that would be 500ah in 5 hours if you pulled it all the time, so you would need a lot of battery if you do average that much for 5 hours. At least 800ah, I would guess, and a way to charge that much use back up in a reasonable length of time. If you use that much for multiple days, that is a lot of charging needed. Solar wouldn't be able to keep up, so you are down to having an engine generator, shore power, or gas generator to cover either the use as it happens, or to recover the batteries once you use that much power.
