Group 24 AGM. Lifeline is generally considered the best brand due in part to lower self-discharge rates (2% per month vs. 5% per month for other brands) when not in use.
Self-discharge rates really only become important if the motorhome sits unused for long periods without being connected to a charging source (solar, generator, engine alternator, shore power), so if that's not an issue for you, you can go with a less expensive brand with little to no loss of functionality. All Group 24 AGM batteries have similar amp-hour ratings and physical dimensions.
