Never make assumptions about " how the public perceive you ". What they see is THE PERSON in front of them and later THE RESULT that person achieves / whether they deliver VALUE and are CLEAN / TIDY / RESPECTFUL of their property and themselves.
Sure you can get a lot more in a van ( I have a small van but it carries a Bane, a portable, a rotary, 100 feet of hose, buckets, chemicals, tools, and more ) but I could just as easily carry a portable with hoses, etc in a small hatchback and get as good a result.
I've known several c/c's who never used a van ( from choice ) but ran very successful businesses.
One of the highest earning c/c's in his country uses a non sign written van and turns up wearing shorts and unshaven................BUT he is a charming and very knowledgable individual and sells HIMSELF to his prospects.
