There are many good 5th. wheels out there. I would suggest you look at Heartlands line of 5th. wheels. I bought the 33' Big Horn with 3 slides and we have found it to be roomy, comfortable and easy to tow. I especially like the hydraulic front jacks and electric rear stabilizers. We are livening in our rig about 6 months a year. Heartland's customer service and warranty issue fixes have been outstanding for us, others may have had different service. Towing with a Dodge 3500 Diesel , 6spd. manual and get 12 to 13 mpg on the average.
PS. If you get or have a diesel truck already, I would strongly recommend you contact "Transfer Flow" in chico Ca. to get a larger diesel fuel tank. They will mail the tanks to your area and give you the name of a shop who can install it. I replaced the original 34 gal tank with a 60 gal tank. Minimizes worry about finding diesel and allows you to pick the best priced diesel.:)
