I tow an enclosed 24' trailer with my Suburban but usually stay with my friend in his motorhome. The pit spaces aren't usually an issue at most D1 races I've been to.
The only byproduct with some downside is that the spectators who wander the pits don't get to see as many cars when they're in enclosed trailers and us racers when between rounds tend to babysit our pit or cool off inside the coach rather than go watch racing in the stands. We tended to do the stands more when the station wagon was the only refuge and it had no AC.
But that is evolution.
