I used to travel as a child/teen in my grandparents RV. Gram & Granddad have a BornFree class C, though they're in their 80's and only use it a few weeks a year now. They used to do the snowbird thing in the winter and take the grandkids for a month or more in the summer. They lived in the RV more than at home once they retired. We are me (Marie), my long term boyfriend, a medium size doodle (don't tell him he's a senior dog; he hasn't figured it out yet), and sometimes a young-teen child. Currently living in central PA. We have been doing some car camping with a tent but finally decided to take the plunge on getting a used RV. So we traded in the little civic for a 2003 Ram 2500 that's all set up for towing already (something about the rear end that I don't fully understand) and has under 100,000 miles.
We've narrowed the choice down to two potential RV trailers at a specific dealership: a 2004 Forest River Wildcat (29 BHBP)- 29 foot 5th wheel with a huge ton of storage space and a gigantic slide and a whole second bedroom with a door for storage or to put the young-teen child when she comes with us. Downsides: the carpet looks like crap and doesn't feel good underfoot plus is probably full of allergens and the fully loaded weight (including full fresh water tank) will be pushing the top end of what the truck can pull according to the documentation we can find AND we'll need to get a fifth wheel hitch installed in the truck AND when we put the slide in, the sound was kinda scary. Other option that I really like is a 2007 Gulf Stream Conquest (275 FBS) - enough beds but MUCH less storage space and a smaller slide (which was quiet going in). It is much lighter and well within the listed towing capacity of the truck. The roof is lower though and it does feel a little cramped without the huge slide. And while there are the same number of beds, the lack of a distinct second bedroom doesn't make the teen-drama-queen very happy. *shrugs* It never bothered me as a kid to sleep on the couch or the above cab bunk so I don't know what her deal is. AND we have to either choose today or take our chances that one won't be there next time we check back. Wish us luck choosing!
