I am not sure what all you are carrying in your unit, and since you didn’t mention year or model, it is difficult to give a full answer. Typically, lithium batteries are about 1/3 the weight of your AGM batteries. A typical solar panel will check in at about 35-40 lbs. Ancillary equipment like SCC’s and Inverters will add another 40 lbs or so. I am probably lighter than my 4 6 volt golf cart batteries in the last rig. We did upgrade our suspension to IS, but matching the 7000 lb axles that came on our unit.
