We have been using open trailers and are now thinking of purchasing an enclosed trailer. We may buy for the future knowing that we will grow and need more space. Right now we could get by with a 7 X 14. However, we have an opportunity to buy a 8.5 X 18 for $1000 more (both new). Does anyone care to share their experiences in handling these size trailers throughout residential communities? The 7 X 14 won't be an issue but I am thinking the 8.5 X 18 may be difficult to get around on smaller streets, especially with cars parked on them. Does the larger one seem to make more sense in the long run? 70% of our customers are residentials. Thanks!
