With the budget you have, you are looking at a much older class A, or a used Class C or a smaller fifth wheel because a large fifth wheel would require a much more expensive truck. You do not want to put your animals in the fifth wheel while you are traveling. They need to be with you in the Class A/C or in the truck. With anything used or older, you will need to set aside money for maintenance. The maintenance costs can be high on an older motorized RV.
Please tell us if you plan to travel a lot or stay in one place for months at a time. Motorized RVs should be exercised.
