We full time (the RV is our only residence) but we also travel as a business venture so our travels vary depending upon need. We try to only travel about 300 miles per day but if the boss says it's important we can do 400/day. If there is somewhere along the way that WE feel might be worth the effort we have done a couple of 500 mile days just so we could play or enjoy that particular destination along the way. We do travel "at least" the speed limit except where the speed limit is 75 or above as we really like 72ish.
