Welcome to this site Solo!
Give us some ideas as to how you plan to live and travel in your rig. For example, will you migrate with the seasons or with your vocation, to parks you already know well? Or will you do some exploring along the way?
If you already know your destinations and their amenities: strong reliable Wi-Fi, good cable TV, etc., then perhaps you can forego some of that technology in your traveling home.
We are still newby's compared to some on this forum, but am SO GLAD we invested in an Aircard (Verizon to accompany our cell phones). OMG you cannot believe how many folks complain about Wi-Fi reception when they post reviews. It's a non-issue for us.
Second, we took the Directv box from our stick home and had it attached to the rig's dish, when we purchased. Eliminates angst when overnighting or when settling in for a couple days at a nice park. We just make sure there is a clear shot at the southern sky to receive a signal. No dissappointments with a park's lack of TV coverage for whatever reason.
Just those two pieces of technology (Aircard and DirecTV) give us mass freedom. Fire up the generator in the middle of an Iowa field, and we can access all the civilization we can handle!
Am hardly an expert in rigs, however we have discovered (over 5 years on the road) that smaller is better. We both sigh wistfully at some magnificently longer rigs, but then listen to their owners vent frustration at not being able to get their 40-footer into, around, or back out of older parks. Forget about most state/federal campgrounds.
We ususally do not need to make reservations for our overnights, as our 32 foot coach fits into just about any space in a park. We tow a small car, and yes, I try to get pull-through spot when we are overnighting. Have much better chance at not-unhooking, the shorter you are.
Do not be afraid of slide-outs, especially if you chose a newer model coach.
Do opt for automatic levelers. Especially as a solo flyer.
Just know that toy hauler rigs are excluded from some nicer, higher end RV parks.
You may never want to purchase a lot in said parks, but you automatically eliminate yourself from renting in some magnificent areas of this country, if your rig is TOO short (under 32 feet) or a toyhauler.
Am confident others will chime in here. The most important thing is to get yourself free, and on the road! Enjoy!
