Which should I buy?

If you haven't already looked at the Rockwood ROO/Flagstaff Shamrock, suggest you take a look. They are one of the more popular brands. We sold our '07 ROO 23SS in May of last year ('13) for $9500 and it was in mint condition and always stored undercover. Agree on checking extra thoroughly for any signs or smells of water/mildew/soft spots. Haven't looked recently at NADA, but our camping buddies sold their '07 Shamrock 19 about 2 years ago and I believe he got about $6000 + or -. I think it would be to your benefit to consider looking in the Midwest area online and see what's available. You could turn the purchase into a mini-vacation to pick it up. If your budget will stretch it, also suggest you look online at RVWholesalers in Lakeview, OH and House of Camping in Chi where bikendan purchased. We bought both our HTT and TT at RVW and after trip expenses saved abut $4000+ on the HTT and more on the TT. bikendan did about the same in Chi. Might be worth investigating. RVW is an excellent company to deal with, no games, good reputation. If nothing else, you can get some good views of what's out there new and if interested they will email you a price. They list MSRP and you can figure around 30%+ off that for the sales price....maybe better this time of the year. Camping season is winding down even in the mid-south and dealers would be happy to move one out. Good luck and happy camping.
