Optima Group 34 might fit.

Vapor lock usually occurs due to heat, if memory serves.

Peace. ~RL

Yes, I believe you're right. [emoticon]

Would you be inclined to pursue this MH?
BTW, good luck with getting the battery size you need.

Downsizing ">

It has to speak to you as in (you).
Ya pays yer money and ya makes yer choices.

If in doubt, back away. There must be a bazillion and one RV's for sale out there.
Just sayin'

Yep yep. Coupla 6's would be nice.
Just measured the box again. 11" high. Odd size box, imo.
I have no problems with modifying the box since it's access is from outside and it rests under the dinette just behind the drivers seat.
Maybe throw in a Group 27 and be done with it.

Actually, a Group 34 battery might be better then a 27. 34 has the same footprint as 24 and roughly one inch shorter in height.

BCI tables shows:

Group 24 -- 200-900 amps.

Group 27 -- 340-810 amps.

Group 34 -- 375-800 amps.

(These are figures for starting batteries, dual-purpose and deep cycle batteries will have different figures but relative difference between each group will be similar.)

1972 Executive Class A on a Dodge M375 chassis with 413 cu. in.

Group 22, although small would suffice. Not too popular it seems.

Yes, it does. However, the fact it happens above 45 mph leads me to believe the OEM pump is sucking air in through a small leak in the fuel line. (Increased RPMs means the OEM pump is running harder, possibly drawing in more air due to increased suction.)

Air being drawn into the fuel line will act just like a vapor lock.

Group 34 appears to lean toward AGM style. Optima keeps coming up.
Dunno, yet, how this style fares with vehicle alternator doing the charging

True dat. Another bench racing point of view is fuel starvation.
Things are well down low but increase demand and it starves out. Clogged filter will do that.

I'm putting Optima BlueTop Group 34 batteries in my boat. 27s are too long and 24s are too tall.

Also, Group 34 batteries appear to be increasingly popular with vehicle manufacturers, possible leading to that size becoming most readily available.
