And what year? Tank sizes changed over the years.

The length of the camper does not always drive the tank size. A 20 footer can have the same tanks as a 30 footer. An ultra small camper, yes they have smaller tanks

Thank you FiveO, It's a 2004 Sunline Solaris 26ft. Also the indicator panel, black water light stays at 2/3 full. While the gray water indicator light will operate properly when emptied.

The only 26ft I see is the T2553. If that's the case then fresh water capacity is 32 gal gray water capacity is 35gal and black water capacity is 30 gal.
Indicator lights are finicky. If your showing 2/3 full on an empty tank then your probes are dirty. If black tank is not well maintained the probes gets dried crud on them which in most cases won't come off. Replacing probes is an easy and cheap job.
I posted a post on installing probes but haven't found it yet. I'll get back to you

This site list some of the models that are close to 26 ft. Still not sure exactly which one yours is, (is the black and white tag still near the door, or look at the vin sticker on the left front) As others have stated it could be different depending on the exact model.

Hi Sunline! I NEED to determine size of my black holding tank for my dear old trailer, a 1994 T2653 Sunline Solaris. Due to Covid19 restrictions the seasonal park will not be opening the public facility, so I need to use my trailer's bathroom this summer. Thank you very much for any advice you can offer!!!!

Hi, I answered your tank size questions in you other post. This one https://www.sunlineclub.com/forums/f...ank-19651.html

My tank shows 2/3 full when empty, I have tried using different stuff to clean the probes and have been unsuccessful. Has anyone ever replaced the probes for the black water tank and if so can you direct me to where and how I can replace them. Also where can I get the new probes? I checked the RV shop in my area and they don’t carry them in stock. Any help would be greatly appreciated.
My trailer is a 2005 model #T2363.

You can YouTube how to replace them. Seems fairly easy.

This product, Happy Camper Extreme Cleaner has worked in many cases to clean the black and gray tank. It is sold in various places, I have not had to buy it in many years. I bought mine to clean out the top of the gray tank as scum can grow on top inside the grey tank too.

I let a camper buddy use some while at a Meet & Greet a number of years ago and his black tank sensors were working by morning. He was then sold and I think even converted to the Happy camper normal tank product.

You need to fill the tank totally and add the chemical (all of it) and then wait a good long time. A day or more if you have very heavy build up. Then be able to dump and flush. This can be hard to do if you cannot dump at home. OR go camping, do it at camp and use the camp bathroom. Ideally a full hook up site, but even being able to dump at the camp is a big help. Some camps allow you to just dump the camper for a fee. Ohio state parks charge $10 for dumping as a point of reference if you are "only" coming to dump. If you camp there, then dumping is free.

I have found the key to having the sensors stay working, once the tank is clean, you have to keep it clean every time you dump. (after each camp out) I have installed internal tank sprayers to make this easier, but a hand wand works as good to spray in extra water to clean the tank when at the dump. Even 5 gallon bucket of water dumped down the toilet when flushing out the tank helps.

Hope this helps

PS. The probes Jim linked are the type Sunline would have installed on a 2005 camper. When you tighten the nut next to the flat washer, it expands the rubber and seals in the tank wall. The wire then is held on by the other nut. The old one may be stuck in the tank when go to loosen the nut, just a slight tap and pry should remove them. Just have a new sensor ready when you go fiddling with an old one. Once you disturb an old sensor it might not seal back up as the rubber may crack.
