Newbie: Recommend Trailer Size for Forestry Roads?

Hello everyone,
Long time lurker, first time poster getting ready to buy my first CT to convert into a mini rv space for the family of 4.
I was close to pulling the trigger on a v-nose 6x10 last week, but after renting a 6x12 uhaul special to try towing with the old '02 Suburban for the first time (mainly to and from a empty parking lot to practice backing up with a friend) I am now a little worried about making the wrong choice in usable size.
A larger part of the trailer's intended use is going to be boondocking in national forests/BLM land out here in beautiful Washington State, where the forestry roads can be somewhat narrow and the chance of a downed tree in the road is ever present.
I would love to hear any recommendations or advice on the following 2 questions, as they are the last couple worries I have keeping me from taking the dive into part of the CT conversion community:
1) Even for my suburban, the 6x10 wheel base sticks out a little less then a foot on either side. Is that going to create issues for me when driving over roads with ruts and muddy shoulders or is it pretty manageable once I get some experience with it?
2) I've looked into trailer dollys as a way of detaching and turning around a trailer if I come up to a downed tree or impasse on a narrow road with no turnarounds close. Does anyone think that would be a feasible plan for a trailer with an estimated final weight of about 1800 lbs if I make sure to back up to a (relatively) flat section of the road with not too many potholes (dirt and/or gravel road)?
Thanks for any help you can give, and sorry about the long post! hope to join your ranks soon and document my build. Hoping to show the build up from a more novice perspective.
