Hey Ron, in looking at zb39's RV photo of the passenger side, the second step appears to be huge. Is yours like that? The drivers side of yours looks more doable for an old guy/woman.
It is a pretty bigstep... I had DW test it out as she has a torn meniscus in her left knee and she had no problem. I have one too, fused left ankle and bad back, but easy for me too. Anticipating surgery for her so alternate is for her to enter and leave through the coach door. In fact, researching adding additional grab railing inside coach to the left, for her and me. likely will be taking nice finished piece of wood and bonding to the paneling for a nice ADA railing. I believe ease of access, nice layout, and not having to move furniture (two recliners and L section of couch in MS) plus a single level layout in the coach made this an easy decision for DW and me. If you're starting to look, easy access to the coach and to storage are huge considerations, good room to move around in the bathroom (toilet and shower), easy access around the bed to make it, and easy access to interior storage. One thing about me, I can't stand rattles, so likely will place towels over silverware, utensils, and miscellaneous drawer.
One thing I mentioned to DW is not sure how much I'm keen on not being able to back up with flat towed Jeep, so gave her a heads up might want 12 to 14 ft open car hauler. I have a 20ft enclosed one, but not keen on the extra length. We'll see on that.
Another point is hard assessment on what we want and need to carry WRT cargo. Emptying out the MS proved there was a lot of ballast we never used, so we both will be scrutinizing the 3,800lbs of cargo we have remaining.
Been reading the International and Allison operators manuals getting acquainted with features. Looks like the Allison 2500 is a 4th or 5th gen electronic controlled transmission that has performance and economy modes, and options of course to lock out top overdrive (6th) and manual downshift to direct drive (4th). We have a winter storm warning with sleet and ice, so there will be a delay in first trip out. Might be without the Jeep as braking system still enroute and it will need to be wired in and installed.
As I've seen mentioned in several posts and in the marketplace, there are deals showing up where folks are figuring out "camping" isn't their bag. While I was still active duty in the US Air Force. I chose to live in our RV for over 6 years, two assignments, so have a pretty good Insight into the practical side of full timing. I saw numerous instances where folks spent big money on RV setups, just find out they didn't like it or physically couldn't do it. Sad, but a reality, is there are deals to be had a lot with this and I anticipate there may be a glut of deals with COVID.
So please feel free to ask questions and offer comments as we make our way through this new journey going from 5th wheel to motorhome. I plan on providing honest feedback on the RV, both pros and cons as we gain experience with it.
Cheers, Ron
