Each of us are a little different, our activities are a little different and POI's are too. WE did AK and we were gone for ten weeks. No towed, would I do it again?, no way. Take for instance the Oceanographic Museum in Seward, easy to get to from the City Campground in a vehicle, but if you leave your spot in the campground, it is open for the next camper. Driving to many sites all over the country and parking a RV is a pain.
DW and I each have a DD, hers is an SUV and easy for her to enter and exit. Mine is a Suzuki GV and easy to tow. I also have a Sidekick but it is in the middle of restoration and "may" go to the DGS in a year. He may get the GV with all the bells and whistles. I love both of the Suzi's but the sidekick is easier to tow. Regardless, we seldom go anywhere without one or the other. I guess I should add, we are both disabled. I used to say partially disabled but no longer, no incentive to hike for miles with the DGKs, they are able to fend for themselves and I'm(not willingly) admitting I can no longer get out and explore. My balance went wacky about a year ago, seems I have a form of viral vertigo.
