Standard Group 34/78 batteries are 10.25" long.  This is the size we had in our coach before I replaced them.

Standard Group 31 batteries are 13" long.

I think your battery rack is probably sized for Group 34/78 batteries, but best wait for confirmation from another member.

My 2001 U320 has 3 Optima Yellowtop group 31.  That may not be the same as yours.

Randy,

Group 31 series are larger commercial batteries. I had to build another battery tray for them to fit. The coach came with group 34s but my AZone dealer made me a deal (always ask for a discount if buying 3 batteries). I now have almost 3000 CCA so winter cranking was in the back of my mind when I decided to change horses. I went with the Duralast after comparing weight between competing batteries. They weighed 60 lbs each or about 5 lbs more than others I looked at. With batteries, usually the more they weigh, the better they are.

The $300 price was including trade in. They were fine with smaller batteries for the core.

As you can see from the photos, the tray is quite a bit larger and took quite a bit of work to make and install. I had to turn the batteries around so the positive is now at the rear bumper as it was too close to the hyd reservoir.

The cables are OEM Foretravel or I would have changed the way they are connected.

I always use GasBuddy ahead of time and if I can save $0.02/gal I will head a bit out of my way. I comparison shop for everything and always check the menus on Yelp before deciding on a restaurant. Every Indian rides a buffalo in my book.

Duralasts and optimas are both made by Johnson controls.

My cars Bosch agm's are made on the west coast by Johnson controls and on the east coast by east penn.

Hot weather and high under hood temps on my car killed the parallel plate construction Bosch AGM battery in three months.

3 year warranty.  They offered a refund.  I took another one.

Unknown use conditions showing issues out of massive quantities of units sold may or may not show an issue,

Does Foretravel still use Optimas new?

My off road racing buddies use the optimas as far as I know.  So do the boom boom stereo young guys as they produce power quickly for their base speakers.  And a capacitor
