E way bill doubts on Van Sales

Suppose, if we are having retail Van Sales ( Door to door of shops); i.e. taking orders and instantly providing the goods from Van and providing manual bill. 

Now the doubt is , If Van sale billing values of each shops are not exceeding the value of Rs. 50,000; 

Is there E way bill required?

Since the value of goods loaded in Van will be more than 50,000 (apprx 1 -1.50 Lakh); How can we disclose the documents, if the GST Officers asked in transit time on road?

We are maintaining Van Stock Register.

Is it required to take E Way bills in such cases while uploading goods in Van?

Hope to get an apt answer in this regard as soon.
