Hello, I have a 1994 Metorite Starcraft popup 1140lbs on spec. I removed the battery and propane tank from the tongue as I do not need them. Have I made the tongue weight too light now? Will I be ok if I just pack everything forward or do I need to add weight to the tongue? Any suggestion on how to do that if so? I got a side swivel jack so it be hard to mount a tongue box. Im getting an antisway bar installed. I don't have experience towing this or anything. Just looking to make this safe. Thanks.
