I will update my stars if they do a current update. ### 5/5 — Reference for the multitude of factors *2023-05-25, version 2.0.5* Yes yes, a side kick like this versatile RV Reference app is a team player to have when the opposition has the upper hand. Defense, like the Steel Curtain, has a winning element associated with its ability to provide protection in the most uncertain & tense goal-line stances. Not allowing any advancements with the intent to drive it back into a safe zone is not only comforting, but necessary to ensure success! Everyone’s curtain should have density to prevent unwanted defeats. The gritty details are in the dirt, or mud when it is wet. ### 1/5 — Upset *2022-09-01, version 2.0.5* I am more than a little upset that I was charged for purchasing this app when it doesn’t say anywhere on the description or at the top that it costs money. So far it has not been useful to us for helping our motorhome. ### 5/5 — Very informative *2022-08-14, version 2.0.5* Simple accessories lots of clear concise easy to understand and to teach others love it ☺️ ### 4/5 — NRVIA Certified Inspector *2020-06-01, version 2.0.0* This is a great app for newbies to learn and their RV. If you are.a DYI type individual, this app makes for a good reference. Great for inspection to relay information to clients. Northeast RV Inspections will continue to use this app in the future. ### 5/5 — 30 year Master Certified RVIA tech *2018-06-24, version 2.0.0* Great app, will be recommending it to my customers during their walk through/ demo ### 5/5 — Great RV information *2017-07-27* Have used this app since first available. Great app. Needs to be updated to 64 bit for New IOS 11 ### 5/5 — General RV Information *2016-10-23, version 1.3* Just starting out is hard because of the overload of information you receive from friends, family, other rv acquaintances, etc.. This app provides a great reference to fall back on when the data just seems to get lost in that black hole we call a brain. I appreciate all the effort expended to create this very helpful app! ### 2/5 — For beginners *2016-10-05, version 1.3* For new Rv owners for very basic information ### 1/5 — Missing info *2016-04-02, version 1.3* Lots of things are not explained. For example, it tells you how a refrigerator works, but not how to operate. Also includes no instructions for generators or Awnings. ## Frequently asked questions about RV Pocket Reference ### What kind of information does the RV Pocket Reference app provide?
