Hello DIY Users - After studying Transit’s new “All Wheel Drive” chassis and Thor’s B+ Compass RV for over a year now, I finally completed my In-Depth review and would like to share my findings and images with others on this forum to include a Dual Battery Lithium System I designed for RV's and my Compass.

A long awaited feature for Transit owners and the RV industry is Transit’s “All Wheel Drive” chassis. AWD allows RV owners to venture off paved highways, visit remote locations or even extend their traveling season into Winter. However there are some restrictions owners need to adhere to.

In this review, we’ll also look at the Transit’s chassis with its powerful Eco Boost V6 engine and discuss Transit’s 10 speed transmission and five Drive Modes. I’ll also discuss Transit’s unique “Low Slung” chassis design and how it provides the best handling chassis for B+ RV’s. We’ll also look at the many advantages of having a Transit gas RV over a diesel chassis.

I’ll cover dozens of Thor upgrades and improvements I made to both remedy factory errors and design problems. Just a few of my many upgrades was installing a macerator system to avoid dealing with the monster 4” hose. Adding a drip channel over the slide, to prevent water leaks, look at the new RVMP 4000i Flex Power generator advantages over an Onan. Share my “Anti-Winterizing” upgrade which avoids winterizing using Marine / RV heaters to heat the entire coach and its plumbing in Winter. Disclose dozens of potential trouble areas found in the Compass.

In this article - I’ll relocate the Relion lithium battery from the outside step location to inside the coach. We’ll look at RedArc’s 40 amp battery charger problems where it continues to charge the house battery when the engine is off, plus the absence of a charger for the engine batteries when plugged in. Why there’s no longer a “jump start” feature on the Compass. We’ll examine Relion’s Bluetooth-less lithium battery and how it can leave you stranded in cold weather with no means to move the slide in or even start the generator. Discuss why Thors 100 watt solar panel only puts out 10-20 watts most of the time, plus much more. Revel a tankless water heater problem when Thor incorrectly routed the recirculate line in error to the pump inlet, plus much more.

I’ll also share my new “Dual Lithium Battery System” I designed for RV’s and installed in my Compass. This system incorporates two separate lithium battery systems, a “Primary” “Inversion” system, used solely to create 120 volts for the RV’s, AC unit, Micro etc. with a capacity from 4,000 -12,000 watt-hours, plus a “Secondary” 100 ah or 240 ah 12 volt lithium system which is dedicated to power the Compass’ 12 volt devices such as her slides, refrigerator, furnace, pumps etc.

I’ll look forward to your comments, thoughts and questions on this thread.
