I have a 2007 Lance 825. Love it but for offroad use wouldn't it be better to have a popup for a lower center of gravity? Some times when we go down dirt roads it feels a little tippy but that could just be my imagination. This is on a GMC 2500HD so we are well under our load capacity. I have never come near filling up the 14 gal. black tank however we always fill up the gray tank especially using the shower.
I think the Northstar is 5 gallons because its tank is removeable to dump anywhere. I would rather have a 25 gallon gray tank and a removeable 5 gallon black that I could flush anywhere or dump in an outhouse.
