B+ motorhomes

36 in is the width of the sofa being a sofa...so I know if I put in the twin I won't be giving up any more aisle room. The sofa is fullsized when open but I don't need that much with just me. I don't think the BT was designed for off road...I was however pleased not to have to deal with carpet.....Would love to think it could handle a few of the tamer dirt roads out West. It would make for more interesting Boondocking. I use the crates for the smaller dogs as I travel...I have a fear of one of them in their excitement of camping to make the mistake of forgetting obedience and trying to jump down without a leash at a rest stop or restaurant......I carry a couple of the inexpensive soft crates "just in case" - they are also so easy to carry. The beige cover on the sofa is just a thick bedspread. I have used it long enough for it to have sun fade across the top of the sofa...but it does protect the couch! You guys keep posting and keep inspiring me :) PS: their are four dogs altogether and my Blondie is expecting a litter in the beginning of April...so the numbers will all depend on if I decide to keep one of her pups for me to show........
