Spin Welding
I知 about to get tanks. I got a little sticker shock on the spin weld tools.
The grey and black tanks are ABS. Can稚 I just use ABS glue?
Any thoughts on what to do are much appreciated.

I'd guess you would be OK with ABS glue. I've repaired cracked ABS dash boards with ABS glue backed up with fiberglass window screen and it works fine. Try a little experiment: glue a little scrap ABS to your tank using ABS glue (leave a bit extended past the tank edge) let it cure and then use the little ABS flap to support the weight of the tank. If this treatment doesn't pull the scrap off the tank in 3 or 4 days you'll be good to go. As to spin welding, I've done it on the translucent waxy surfaced tanks and had good luck spinning the weld with a router. It makes sense to me that the same procedure would work for ABS.

ABS glue would be correct for ABS tank and DWV plumbing. If you have an ABS tank and PvC plumbing you need a specific glue for ABS to PVC.
The tank pictured above is HDPE (polyethylene). There is no glue that will stick to it. Spinweld is the way to go.
I will be buying the tool when I get ready. I called the "local" RV shop and they wanted $125 to install two fittings. Chuck that. I can get the tool for $100.

I am assuming that you need to install plumbing fittings in your tanks moons ago I used glue and after about three years the joint cracked and leaked blacktank contents down parkway replaced tank and installed grommets sold moterhome 7 yrs later no leaks put 3 tanks in new bus used grommets in all no leaks.

I’m working with Custom Roto-Molding through Tank-Mart. I was told $10 to weld each fitting. I’ll update this when I get numbers.

The price of tanks seems fair, but if you get lots of customization it痴 gonna cost. For instance, $200 for a 35 gallon tank. Then $10 per spin weld fitting. So For my black tank I知 getting 4 sensors, a jet cleanout, a vent and threaded toilet flange hole. $270 +$60 to ship.
I was going to get ABS Icon tanks, shipped free through camperID, but in the tight spaces I知 putting tanks, the rotomolded tanks were offering more capacity for the space I have.
I want to say that tank-mart.com and Custom Roto-Molding Inc. have been great to work with.

Recpro’s black tanks are the same price. I’m going to take the hit on shipping. I’m using a shoehorn and a saw ,to fit them and getting the biggest that will fit, so I’m doing it. Seems like I’m doing a lot of that. I guess that’s an unforeseen consequence of being on a short bus.

The Recpro tanks I have been looking at are 100 gallon tanks that are two for $509 shipping included .
I understand the space issues. My first bus had baggage bays that were 12' x 8' by 3.5'
I had plenty of room for tankage, electrical and plumbing in the bays with lots of storage space left.
I am definitely having to work harder to find space than I did on my Eagle.

The addition of a shower changed the whole water use and supply dynamic. I知 definitely going to be working on an ultra low flow shower head option. Garden sprayer.

Here is a copy of the Marine 5200 sealant technical data sheet which shows the shear strength when used on various materials. The first value is in PSI, the second is in Kg/square cm. You will notice that while it will stick to polyethylene it doesn't stick very well--not something you want to risk. Spin weld is still the best answer. See my post above dated May 12, 2012 and my build thread for some do's and don't's here: https://nomadicista.org/viewtopic.ph...2658&start=180

I did a little homework for you. Here is a report from an "actual user" straight from the HF site:

Durability
Great Value
Features
So far it's worked for several hours. Working with HDPE.
I used to weld HDPE panels together, as well as weld fasteners in place. I made an Ebike Battery box. I'll start with the CONs: The attachments aren't great for plastic welding. They're good for heating plastic, but don't aid in using plastic welding sticks. No aftermarket attachments available that I could find. It's loud? I guess? Pros: I only used level 5, and level 5 heat was more than enough for HDPE. The device heats up quickly. Had rubber padding on the device to rest it while you're not actively using it. Easy to use, even for my first weld.
