Forest River site says 440 pounds for a 291. But that probably doesn't include any of the options; nor full tanks, nor your personal items. I would think your tongue weight will be north of 500 pounds. You might want to consider 800 pound bars. We have a tongue weight of about 500 pounds; have 800 pound bars; works wonderfully.
