Looking for dog breed the travels well while Rving

We have a 4yr old Goldendoodle. The day got him he was 9 wks old. His ride home that day was 100 mi. He has always loved riding and going places, including the vets. He has ridden as much as 800 mi in a day without a problem whether in the back seat of my wifes car or our crew cab. He's not a yappy dog and would lick you to death before anything else
