The brackets in the previous post were to tie the top of the refrigerator to the wall. The intent was to to screw them to the side of the fridge but there wasn't any metal. So I made some large metal corners (material came from the scrap heap) and used VHB tape to secure them to the fridge. Then I screwed the brackets to the plates. Went for a drive and everything is hell-a-stout. I'm tying the fridge to the van because I'm using it as structure to hold my cabinet plus there is minimal clearance for the condenser coils so I can't have any motion relative to the van wall. Pictures:

After the drive (fall colors are awesome, BTW), I checked some of my under-hood components. Everything is looking good. I can't wait to get my fresh water tank mounted and plumbed to the water heater. It was warm to the touch so it shouldn't take a lot of engine coolant to get the water hot. Question: Does anyone know where to plumb it into the engine coolant lines? Maybe a solenoid operated heater control valve would be good.

Hein,

Great conversion and write up! Would you mind providing a link or exact name of the thinsulate insulation you used? The website does not seem clear as to what product is ideal.

Thanks!

Thank you for asking.

I was lucky to get GeorgeRA's leftover MA6700 which he purchased for his van. It wasn't quite enough so I got some SM600L through a contact at 3M. SM600L is from the Automotive group and MA6700 is from Marine. They are the same material except SM600L has black scrim on both sides.

I am currently working with 3M to acquire a number of master rolls of SM600L. It takes about a 1/4 of a 60" wide roll (45feet) to insulate a typical Sprinter. I will sell Thinsulate to DIY Sprinter enthusiasts via this forum. Prices will be competitive and you will be able to order a smaller quantity based on your needs. Lead time at this point appears to be at least 7 weeks.

Picked up some angle and flat bar. I was going to wing it on the fresh water tank support but doing a bit of CAD led to some significant changes. The model is missing fittings/hardware and may need some dimensional adjustments but the general concept is defined. This post shows the location for the tank.



Edit: I'm not sure the pump will fit there. Might have to move it around the corner and onto the end of the tank... I also read that a loop in the suction line is recommended.

I found about the Isotemp by reading your build thread. I was impressed by how you had it mounted so that got the wheels turning. Thank you!

I did a little test fit of my fresh water tank hangers just now. 1 1/2 flat bar bent into an L shape that will go into a slot and hook over a floor cross member. The bottom the hanger will be bolted to the frame that goes around the bottom of the tank. See above. Pump will probably have to move again. It's going to be tight.

There could be 35 lbs of static weight per tab with full tank of water; I assume you will attach these tabs with bolts to the crossbars.

How are you planning to fill up the tank?

George.

Thanks for doing the math, George. Some supports will see a little more or less because they are not equally spaced. And I am planning to weld an HDPE plate to the tank wall to hold the pump. The bar is 1 1/2 by 1/8 thick so no problem there.

Somewhat concerned about tearing out the corners of the cross member. I'll likely run a bolt w/fender washer into the short leg of the angle through the large hole in the cross member. More pictures to come.

I think a gravity fill through the side of the van might work. The fill will be right below the trim panel. And I plan to vent each corner. Once again, I hadn't really thought about it too much until I had read your posts. I have these items in my cart ATM.

First, I must compliment you on your clever workmanship and design techniques. (I wish I had a CNC Router when I was building mine).

A little tip... The fresh water tank appears to be made of white Polypropylene. However the action of daylight can cause an algal growth within the tank. Even when mounted under the van. Here in NZ it is a requirement to comply for Certified Containment Certificate to ensure that all fresh water pipes and fixed tanks are opaque to light.
Sooo... We either make the tank out of black polypropylene or paint the tank and any clear plastic hoses under the van with black paint. Problem solved!

Cheers

Ross

You could consider adding steel angles with bolts going through the cross member to distribute the weight. I did it for my fresh water tank.
