Hey RV gurus! I am interested in buying a travel trailer, used preferably. Looking for brand, features, and thongs-to-avoid recommendations. Here is what my general requirements are: Under 6K lbs -- 1500 Hemi 4WD towing 26+ Ft Sleep at least 6 Slider optional The queen bed needs a wall between it and rest of trailer My budget is $20K Not picky on brands, but curious what you think is a good or bad one. Any decent research sites I should go to? Thanks!
