Hello and welcome to the forum. I think that a 3/4 ton truck, maybe a gas motor with at least a 6.0 liters, diesel would be even better, and a 5th wheel around 30-31 foot would probably fit your needs. If you can keep the weight around 10,000 lbs. or less you would have the best all around combo. As others suggested, going to RV shows, and even visiting local dealers, is the best way to get your information. I know that personally I have more time than money, so if you use your time wisely, you should be able to find the combo that you want and save money. Also, you came to the right forum, as this place has a wealth of information from a variety of people,ages and experience.
