Welcome to the forum.
If you go to a Ford dealer looking for a truck, would they say you should buy a Chevrolet? No, they will try to sell you their product.
Same thing with a RV. They want to sell you what they have on display.
Check the dealers in the area you are willing to travel for the purchase.
Find a model(s) that fit your needs and wants. Every brand has pros and cons.
Then ask questions/opinions about them.
There is a big selection available, check out as many as you can and don't be in a hurry to buy.
There is a lot of experience and information available on the forum. Don't hesitate to ask questions.
When you find something you like, let us know what you will use as tow vehicle. Someone will help you determine if it is capable.
Many dealers/sales people will tell you a F-150 or 1500 series can pull just about anything. They just want to make a sale.
Take your time and use the search as a learning experience. Most members on the forum are happy to share their experience.
