Yup. Only time I ever exhausted 200 gal of water was on some commercial jobs.I had a 3500 with the hydracradle reel tank plus another 100 gallon wheel well tank. Honestly one of my favorite setups because I pretty much never ran out of water. And if I did it was time to go home for the day.
I always carried 200 gallons of soft water because half the places around here have shit for water.I've never understood needing more than 1 water tank. 99% of places have a water hook-up. I'd rather have more tools on the truck for cleaning more surfaces.
I added extra leaf springs to my Astro van several years ago because of carrying extra weight and had a much better ride and no problems with anything suspension related. I also added an onboard RV water softener.and dont even think about beefing up the suspension. It doesnt work well
