Must-haves for Van or SUV as tow vehicle?

So I have been doing some thinking, and I think I’m putting a Class C back on my list of possibilities... I’m honestly more attracted to the class c idea for the simplicity of not moving pets back and forth between a tow vehicle and a trailer, and I feel more comfortable with the idea of driving an ambulance sized vehicle with something little behind in comparison to a potentially large tow vehicle towing something even bigger behind... I’m sure I could learn either system though... so I’m back at my original drawing board of older class c vs tow vehicle/ travel trailer combo... so I must continue my research.. I still welcome any advice and am so thankful for everyone’s words of wisdom so far!!!
